# Python glob() #

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 ###

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

### print(glob.glob(r’ ./\*’) )本级所有目录 ###

>>> print(glob.glob("./*"))

### print(glob.glob(r’ ./ \* . \*’) )本级所有dll ###

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

### print(glob.glob(r’ C:/ \* ') )C盘所有目录 ###

>>> print(glob.glob("C:/*"))
    ['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 ###
