This article mainly introduces the use of Python traversal C disk DLL file method, with the Fnmatch module to achieve a very simple, the need for friends can refer to the
Python fnmatch is really worry, compared to the Java FilenameFilter, is really good too much, you do not need to implement what interface.
Fnmatch with Os.walk () or Os.listdir (), you can do too much and use it fairly easy.
