夏夜，蟋蟀劲鸣，星光灿烂，月光清澈。孩提时的晨在小山上快活的玩味着每一朵花，每一株草，亦或躺在绿油油的草地数星星。一切都是那么的美好，那么的惬意。
>>>importos导入模块 >>>os.listdir("d:\\python25")列出所有目录和文件

True
>>>os.path.isdir("D:\\python25\\odbchelper.py")
False
>>>os.path.isfile("D:\\python25\\odbchelper.py")
True 当前目录 >>>os.getcwd()
'D:\\Python25' 通配符的使用，引入glob IDLE1.2.1
>>>importglob
>>>glob.glob('D:\\python25\\*.exe')
['D:\\python25\\w9xpopen.exe','D:\\python25\\python.exe','D:\\python25\\pythonw.exe']
>>>glob.glob('D:\\python25\\py*.exe')
['D:\\python25\\python.exe','D:\\python25\\pythonw.exe']
>>>
本文py中的目录与文件判别代码到此结束。业精于勤而荒于嬉，行成于思而毁于随。小编再次感谢大家对我们的支持！
