在过去的2020年，Python赢得了年度TIOBE编程语言奖，成为过去一年最受欢迎的编程语言。在数据科学和机器学习等领域中，被广泛使用。
正值“金三银四”招聘季，小F给大家整理了50道Python面试题，还有相对应的答案，来帮助大家更好的了解和学习Python。
▍1、什么是Python？为什么它会如此流行？
Python是一种解释的、高级的、通用的编程语言。
Python的设计理念是通过使用必要的空格与空行，增强代码的可读性。
它之所以受欢迎，就是因为它具有简单易用的语法。
▍2、为什么Python执行速度慢，我们如何改进它？
Python代码执行缓慢的原因，是因为它是一种解释型语言。它的代码在运行时进行解释，而不是编译为本地语言。
为了提高Python代码的速度，我们可以使用CPython、Numba，或者我们也可以对代码进行一些修改。
1. 减少内存占用。
2. 使用内置函数和库。
3. 将计算移到循环外。
4. 保持小的代码库。
5. 避免不必要的循环
▍3、Python有什么特点？
1. 易于编码
2. 免费和开源语言
3. 高级语言
4. 易于调试
5. OOPS支持
6. 大量的标准库和第三方模块
7. 可扩展性(我们可以用C或C++编写Python代码)
8. 用户友好的数据结构
▍4、Python有哪些应用？
1. Web开发
2. 桌面GUI开发
3. 人工智能和机器学习
4. 软件开发
5. 业务应用程序开发
6. 基于控制台的应用程序
7. 软件测试
8. Web自动化
9. 基于音频或视频的应用程序
10. 图像处理应用程序
▍5、Python的局限性？
1. 速度
2. 移动开发
3. 内存消耗(与其他语言相比非常高)
4. 两个版本的不兼容(2，3)
5. 运行错误(需要更多测试，并且错误仅在运行时显示)
6. 简单性
▍6、Python代码是如何执行的？
首先，解释器读取Python代码并检查是否有语法或格式错误。
如果发现错误，则暂停执行。如果没有发现错误，则解释器会将Python代码转换为等效形式或字节代码。
然后将字节码发送到Python虚拟机(PVM)，这里Python代码将被执行，如果发现任何错误，则暂停执行，否则结果将显示在输出窗口中。
▍7、如何在Python中管理内存？
Python内存由Python的私有headspace管理。
所有的Python对象和数据结构都位于一个私有堆中。私用堆的分配由Python内存管理器负责。
Python还内置了一个的垃圾收集器，可以回收未使用的内存并释放内存，使其可用于headspace。
▍8、解释Python的内置数据结构？
Python中主要有四种类型的数据结构。
列表：列表是从整数到字符串甚至另一个列表的异构数据项的集合。列表是可变的。列表完成了其他语言中大多数集合数据结构的工作。列表在[ ]方括号中定义。
例如：a = [1,2,3,4]
集合：集合是唯一元素的无序集合。集合运算如联合|，交集&和差异，可以应用于集合。集是不可变的。()用于表示一个集合。
例如：a = {1,2,3,4}
元组：Python元组的工作方式与Python列表完全相同，只是它们是不可变的。()用于定义元组。
例如：a =（1,2,3,4）
字典：字典是键值对的集合。它类似于其他语言中的hash map。在字典里，键是唯一且不可变的对象。
例如：a = {'number'：[1,2,3,4]}
▍9、解释//、％、* *运算符？
//(Floor Division)-这是一个除法运算符，它返回除法的整数部分。
例如：5 // 2 = 2
％(模数)-返回除法的余数。
例如：5 ％ 2 = 1
**(幂)-它对运算符执行指数计算。a ** b表示a的b次方。
例如：5 ** 2 = 25、5 ** 3 = 125
▍10、Python中的单引号和双引号有什么区别？
在Python中使用单引号(' ')或双引号(" ")是没有区别的，都可以用来表示一个字符串。
这两种通用的表达方式，除了可以简化程序员的开发，避免出错之外，还有一种好处，就是可以减少转义字符的使用，使程序看起来更简洁，更清晰。
▍11、Python中append，insert和extend的区别?
append：在列表末尾添加新元素。
insert：在列表的特定位置添加元素。
extend：通过添加新列表来扩展列表。

break：在满足条件时，它将导致程序退出循环。
continue：将返回到循环的开头，它使程序在当前循环迭代中的跳过所有剩余语句。
pass：使程序传递所有剩余语句而不执行。
▍13、区分Python中的remove，del和pop？
remove：将删除列表中的第一个匹配值，它以值作为参数。
del：使用索引删除元素，它不返回任何值。
pop：将删除列表中顶部的元素，并返回列表的顶部元素。

在Python中，我们可以通过下面两种方式进行注释。
1. 三引号'''，用于多行注释。
2. 单井号#，用于单行注释。
▍19、!=和is not运算符的区别？
!=如果两个变量或对象的值不相等，则返回true。
is not是用来检查两个对象是否属于同一内存对象。
<section style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;">lst1 = [<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">1</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">2</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">3</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">4</span>]<br />lst2 = [<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">1</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">2</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">3</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">4</span>]<br /><br />lst1 != lst2<br />><span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">False</span><br /><br />lst1 <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">is</span> <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">not</span> lst2<br />><span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">True</span><br /></section>▍20、Python是否有main函数？
是的，它有的。只要我们运行Python脚本，它就会自动执行。
▍21、什么是lambda函数？
Lambda函数是不带名称的单行函数，可以具有n个参数，但只能有一个表达式。也称为匿名函数。
<p style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;">a = <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">lambda</span> x, y：x + y <br />print(a(<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">5</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">6</span>))<br /><br />> <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">11</span><br /></p>▍22、iterables和iterators之间的区别？
iterable：可迭代是一个对象，可以对其进行迭代。在可迭代的情况下，整个数据一次存储在内存中。
iterators：迭代器是用来在对象上迭代的对象。它只在被调用时被初始化或存储在内存中。迭代器使用next从对象中取出元素。

pickling是将Python对象(甚至是Python代码)，转换为字符串的过程。
unpickling是将字符串，转换为原来对象的逆过程。
▍27、解释*args和**kwargs？
*args，是当我们不确定要传递给函数参数的数量时使用的。
<section style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;">def add（* num）：<br /> sum = <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">0</span> <br /> <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">for</span> val <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">in</span> num：<br /> sum = val + sum <br /> print（sum）<br /><br /><br />add（<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">4</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">5</span>）<br />add（<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">7</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">4</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">6</span>）<br />add（<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">10</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">34</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">23</span>）<br />--------------------- <br /><span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">9</span> <br /><span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">17</span> <br /><span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">57</span><br /></section>**kwargs，是当我们想将字典作为参数传递给函数时使用的。
<p style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;">def intro(**data):<br /> print(<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"nData type of argument:"</span>,type(data))<br /> <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">for</span> key, value <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">in</span> data.items():<br /> print(<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"{} is {}"</span>.format(key,value))<br /><br /><br />intro(name=<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"alex"</span>,Age=<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">22</span>, Phone=<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">1234567890</span>)<br />intro(name=<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"louis"</span>,Email=<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"a@gmail.com"</span>,Country=<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"Wakanda"</span>, Age=<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">25</span>)<br />--------------------------------------------------------------<br />Data type <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">of</span> argument: <class 'dict'><br />name is alex<br />Age is 22<br />Phone is 1234567890<br /><br />Data type of argument: <class 'dict'><br />name is louis<br />Email is a@gmail.com<br />Country is Wakanda<br />Age is 25<br /></p>▍28、解释re模块的split()、sub()、subn()方法？
split()：只要模式匹配，此方法就会拆分字符串。
sub()：此方法用于将字符串中的某些模式替换为其他字符串或序列。
subn()：和sub()很相似，不同之处在于它返回一个元组，将总替换计数和新字符串作为输出。
<section style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;"><span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">import</span> re<br />string = <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"There are two ball in the basket 101"</span><br /><br /><br />re.split(<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"W+"</span>,string)<br />---------------------------------------<br />[<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'There'</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'are'</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'two'</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'ball'</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'in'</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'the'</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'basket'</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'101'</span>]<br /><br />re.sub(<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"[^A-Za-z]"</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">" "</span>,string)<br />----------------------------------------<br /><span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'There are two ball in the basket'</span><br /><br />re.subn(<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"[^A-Za-z]"</span>,<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">" "</span>,string)<br />-----------------------------------------<br />(<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'There are two ball in the basket'</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">10</span>)<br /></section>▍29、Python中的生成器是什么？
生成器(generator)的定义与普通函数类似，生成器使用yield关键字生成值。
如果一个函数包含yield关键字，那么该函数将自动成为一个生成器。
<p style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;"><span style="font-size: inherit;line-height: inherit;color: rgb(128, 128, 128);overflow-wrap: inherit !important;word-break: inherit !important;"># A program to demonstrate the use of generator object with next() A generator function </span><br /><span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;"><span style="font-size: inherit;line-height: inherit;overflow-wrap: inherit !important;word-break: inherit !important;">def</span> <span style="font-size: inherit;line-height: inherit;color: rgb(165, 218, 45);overflow-wrap: inherit !important;word-break: inherit !important;">Fun</span><span style="font-size: inherit;line-height: inherit;color: rgb(255, 152, 35);overflow-wrap: inherit !important;word-break: inherit !important;">()</span>:</span> <br /> <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">yield</span> <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">1</span><br /> <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">yield</span> <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">2</span><br /> <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">yield</span> <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">3</span><br /><br /><span style="font-size: inherit;line-height: inherit;color: rgb(128, 128, 128);overflow-wrap: inherit !important;word-break: inherit !important;"># x is a generator object </span><br />x = Fun()<br />print(next(x))<br />-----------------------------<br /><span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">1</span><br />print(next(x))<br />-----------------------------<br /><span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">2</span><br /></p>▍30、如何使用索引来反转Python中的字符串?
<p style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;">string = <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'hello'</span><br /><br />string[::<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">-1</span>]<br />><span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'olleh'</span></p>▍31、类和对象有什么区别？
类(Class)被视为对象的蓝图。类中的第一行字符串称为doc字符串，包含该类的简短描述。
在Python中，使用class关键字可以创建了一个类。一个类包含变量和成员组合，称为类成员。
对象(Object)是真实存在的实体。在Python中为类创建一个对象，我们可以使用obj = CLASS_NAME()
例如：obj = num()
使用类的对象，我们可以访问类的所有成员，并对其进行操作。
<p style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;"><span style="font-size: inherit;color: inherit;line-height: inherit;overflow-wrap: inherit !important;word-break: inherit !important;"><span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">class</span> <span style="font-size: inherit;line-height: inherit;color: rgb(165, 218, 45);overflow-wrap: inherit !important;word-break: inherit !important;">Person</span>:</span><br /> <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">""" This is a Person Class"""</span><br /> <span style="font-size: inherit;line-height: inherit;color: rgb(128, 128, 128);overflow-wrap: inherit !important;word-break: inherit !important;"># varable</span><br /> age = <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">10</span><br /> <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;"><span style="font-size: inherit;line-height: inherit;overflow-wrap: inherit !important;word-break: inherit !important;">def</span> <span style="font-size: inherit;line-height: inherit;color: rgb(165, 218, 45);overflow-wrap: inherit !important;word-break: inherit !important;">greets</span><span style="font-size: inherit;line-height: inherit;color: rgb(255, 152, 35);overflow-wrap: inherit !important;word-break: inherit !important;">(self)</span>:</span><br /> print(<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'Hello'</span>)<br /><br /><br /><span style="font-size: inherit;line-height: inherit;color: rgb(128, 128, 128);overflow-wrap: inherit !important;word-break: inherit !important;"># object</span><br />obj = Person()<br />print(obj.greet)<br />----------------------------------------<br />Hello</p>▍32、你对Python类中的self有什么了解？
self表示类的实例。
通过使用self关键字，我们可以在Python中访问类的属性和方法。
注意，在类的函数当中，必须使用self，因为类中没有用于声明变量的显式语法。
▍33、_init_在Python中有什么用？
“__init__”是Python类中的保留方法。
它被称为构造函数，每当执行代码时都会自动调用它，它主要用于初始化类的所有变量。
▍34、解释一下Python中的继承？
继承(inheritance)允许一个类获取另一个类的所有成员和属性。继承提供代码可重用性，可以更轻松地创建和维护应用程序。
被继承的类称为超类，而继承的类称为派生类/子类。
▍35、Python中OOPS是什么？
面向对象编程，抽象(Abstraction)、封装(Encapsulation)、继承(Inheritance)、多态(Polymorphism)
▍36、什么是抽象？
抽象(Abstraction)是将一个对象的本质或必要特征向外界展示，并隐藏所有其他无关信息的过程。
▍37、什么是封装？
封装(Encapsulation)意味着将数据和成员函数包装在一起成为一个单元。
它还实现了数据隐藏的概念。
▍38、什么是多态？
多态(Polymorphism)的意思是「许多形式」。
子类可以定义自己的独特行为，并且仍然共享其父类/基类的相同功能或行为。
▍39、什么是Python中的猴子补丁？
猴子补丁(monkey patching)，是指在运行时动态修改类或模块。
<p style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;"><span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">from</span> SomeOtherProduct.SomeModule <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">import</span> SomeClass<br /><br /><span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;"><span style="font-size: inherit;line-height: inherit;overflow-wrap: inherit !important;word-break: inherit !important;">def</span> <span style="font-size: inherit;line-height: inherit;color: rgb(165, 218, 45);overflow-wrap: inherit !important;word-break: inherit !important;">speak</span><span style="font-size: inherit;line-height: inherit;color: rgb(255, 152, 35);overflow-wrap: inherit !important;word-break: inherit !important;">(self)</span>:</span><br /> <span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">return</span> <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">"Hello!"</span><br /><br />SomeClass.speak = speak</p>▍40、Python支持多重继承吗？
Python可以支持多重继承。多重继承意味着，一个类可以从多个父类派生。
▍41、Python中使用的zip函数是什么？
zip函数获取可迭代对象，将它们聚合到一个元组中，然后返回结果。
zip()函数的语法是zip(*iterables)
<p style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;">numbers = [<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">1</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">2</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">3</span>]<br />string = [<span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'one'</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'two'</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'three'</span>] <br />result = zip(numbers,string)<br /><br />print(set(result))<br />-------------------------------------<br />{(<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">3</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'three'</span>), (<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">2</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'two'</span>), (<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">1</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(238, 220, 112);overflow-wrap: inherit !important;word-break: inherit !important;">'one'</span>)}<br /></p>▍42、解释Python中map()函数？
map()函数将给定函数应用于可迭代对象(列表、元组等)，然后返回结果(map对象)。
我们还可以在map()函数中，同时传递多个可迭代对象。
<p style="line-height: 15px;font-size: 11px;word-spacing: -3px;letter-spacing: 0px;font-family: Consolas, Inconsolata, Courier, monospace;border-radius: 0px;color: rgb(169, 183, 198);background: rgb(40, 43, 46);padding: 0.5em;margin-left: 8px;margin-right: 8px;overflow-wrap: normal !important;word-break: normal !important;overflow: auto !important;display: -webkit-box !important;">numbers = (<span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">1</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">2</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">3</span>, <span style="font-size: inherit;line-height: inherit;color: rgb(174, 135, 250);overflow-wrap: inherit !important;word-break: inherit !important;">4</span>)<br />result = map(<span style="font-size: inherit;line-height: inherit;color: rgb(248, 35, 117);overflow-wrap: inherit !important;word-break: inherit !important;">lambda</span> x: x + x, numbers)<br /><br />print(list(result))</p>▍43、Python中的装饰器是什么？
