Python实例属性的优先级分析

class Person(object):
    #类属性
    address = 'earth'
    def __init__(self, name, gender, age):
        #实例属性
        self.name = name
        self.gender = gender
        self.age = age
 
p1 = Person('zhangsan', 'male', 20)
print(p1.name)
print(p1.gender)
print(p1.age)
 
print(Person.address)
print(p1.address)
 
print('********给实例设置address属性********')
 
p1.address = 'China'
print(Person.address)
print(p1.address)
