Python模块学习 ---- glob模块

glob模块是最简单的模块之一，内容非常少。用它可以查找符合特定规则的文件路径名。跟使用windows下的文件搜索差不多。查找文件只用到三个匹配符：’’, “?”, “[ ]”。””匹配任意0个或多个字符；”?”匹配任意单个字符；”[ ]”匹配指定范围内的字符，如：[0-9]匹配数字。

不区分大小写
'.'开头的不匹配

print(glob.glob(r’ . ./*’) )上一级所有目录

1. >>> print(glob.glob("../*"))
2. ['..\Python37-32', '..\Python38-32']

print(glob.glob(r’ ./*’) )本级所有目录

1. >>> print(glob.glob("./*"))
2. ['.\DLLs', '.\Doc', '.\include', '.\Lib', '.\libs', '.\LICENSE.txt', '.\NEWS.txt', '.\python.exe', '.\python3.dll', '.\python38.dll', '.\pythonw.exe', '.\Scripts', '.\tcl', '.\Tools', '.\vcruntime140.dll']

print(glob.glob(r’ ./ . ’) )本级所有文件

1. print(glob.glob("./*.*"))
2. ['.\LICENSE.txt', '.\NEWS.txt', '.\python.exe', '.\python3.dll', '.\python38.dll', '.\pythonw.exe', '.\vcruntime140.dll']

print(glob.glob(r’ ./ . ’) )本级所有dll

1. >>> print(glob.glob("./*.dll"))
2. ['.\python3.dll', '.\python38.dll', '.\vcruntime140.dll']

print(glob.glob(r’ C:/ * ') )C盘所有目录

1. >>> print(glob.glob("C:/*"))
2. ['C:/$360Section', 'C:/$Recycle.Bin', 'C:/360SANDBOX', 'C:/Boot', 'C:/bootmgr'.......]

print(glob.glob(“C:/[PB][RO]”) )C盘所有包含pr/po/br/bo的目录

1. print(glob.glob("C:/*[PB][RO]*"))
2. ['C:/360SANDBOX', 'C:/Boot', 'C:/bootmgr', 'C:/BOOTNXT', 'C:/BOOTSECT.BAK', 'C:/PO', 'C:/Program Files', 'C:/Program Files (x86)', 'C:/ProgramData']

print(glob.glob(“C:/p？O”) )C盘所有包含P_o的目录

1. >>> print(glob.glob("C:/*P?O*"))
2. ['C:/Program Files', 'C:/Program Files (x86)', 'C:/ProgramData']

print(glob.glob(“C://.txt”) )C盘两级目录所有的txt

1. >>> print(glob.glob("C:/*/*.txt"))
2. ['C:/xiaoyi\检索式.txt']
