        name = name.replace(old_word, new_word)  
        name = "/" + name   www.zzzyk.com
        #print os.path.dirname(filename)  
        full_name = os.path.dirname(filename) + name  
        #print full_name  
        os.rename(filename, full_name)

        usage()

        else:  
            # argv[0] is a directory  
            dir = argv[0]  
            # traversal it  
            traversal_dir(dir, old_word, new_word)  
  
  
if __name__ == '__main__':  
    main(sys.argv[1:])  
 

补充：Web开发 , Python ,

上一个：python enumerate用法
下一个：Python中二进制数据处理模块struct使用
