python 递归遍历文件夹详解编程语言

#!/usr/bin/python 
 
import os.path 
 
 
def readXmls(folder): 
    #三个参数：分别返回1.父目录 2.所有文件夹名字（不含路径） 3.所有文件名字 
    for parent,dirnames,filenames in os.walk(folder):     
        for dirname in  dirnames:                      
            print("parent is:" + parent) 
            print("dirname is" + dirname)             
            #readXmls(os.path.join(parent, dirname))这句不能有！！！ 
        for filename in filenames:                       
            print("parent is:" + parent) 
            print("filename is:" + filename) 
            print("the full name of the file is:" + os.path.join(parent,filename)) #输出文件路径信息 
 
 
if __name__ == '__main__': 
    readXmls('xmlfiles') 
 
 
 

－－－－－－备注－－－－－
os.walk方法本来就是递归，调试了很久也没搞明白……
