Python 递归处理文件和文件夹代码详解

删除目录下的svn代码：

#!/usr/bin/env python  
#coding=utf-8  
import sys, os, stat  
def walk(path):  
    for item in os.listdir(path):  
        subpath = os.path.join(path, item)  
        mode = os.stat(subpath)[stat.ST_MODE]  
        if stat.S_ISDIR(mode):  
            if item == ".svn":  
                print "Cleaning %s ..." %subpath  
                print "%d deleted" % purge(subpath)  
            else:  
                walk(subpath)  
def purge(path):  
    count = 0
    for item in os.listdir(path):  
        subpath = os.path.join(path, item)  
        mode = os.stat(subpath)[stat.ST_MODE]  
        if stat.S_ISDIR(mode):

        else:  
            os.chmod(subpath, stat.S_IREAD|stat.S_IWRITE)  
            os.unlink(subpath)  
            count = 1
    os.rmdir(path)  
    count = 1
    return count

    print "Usage: python cleansvn.py path"
    sys.exit(1)
