Python之文件目录遍历实例代码如下：

1. import os, sys  
2.  from stat import *  
3.   
4.  def walktree(top, callback):  
5.      recursively descend the directory tree rooted at top, 
6.         calling the callback function for each regular file 
7.   
8.      for f in os.listdir(top):  
9.          pathname = os.path.join(top, f)  
10.          mode = os.stat(pathname)[ST_MODE]  
11.          if S_ISDIR(mode):  
12.               Its a directory, recurse into it  
13.              walktree(pathname, callback)  
14.          elif S_ISREG(mode):  
15.               Its a file, call the callback function  
16.              callback(pathname)  
17.          else:  
18.               Unknown file type, print a message  
19.              print Skipping %s % pathname  
20.   
21.  def visitfile(file):  
22.      print visiting, file  
23.   
24.  if __name__ == __main__:  
25.      walktree(sys.argv[1], visitfile)
