【Python】三种遍历文件目录的方法

#coding:utf-8# 方法1：递归遍历目录import osdef visitDir(path):    li = os.listdir(path)    for p in li:        pathname = os.path.join(path,p)        if not os.path.isfile(pathname):    #判断路径是否为文件，如果不是继续遍历            visitDir(pathname)        else:            print pathnameif __name__ == "__main__":    path = r"/Users/GaoHongxing/Desktop"visitDir(path)          # 方法2：函数递归 os.path.walk()import os, os.pathdef visitDir(arg, dirname, names):    for filepath in names:        print os.path.join(dirname, filepath)        if __name__ == "__main__":    path = r"/Users/GaoHongxing/Desktop"    os.path.walk(path,visitDir,())# 方法3： 函数递归os.walk()import osdef visitDir(path):    for root, dirs, files in os.walk(path):        for filepath in files:            print os.path.join(root, filepath)            if __name__ == "__main__":    path = r"/Users/GaoHongxing/Desktop"     visitDir(path)  """os.path.walk()与os.walk()产生的文件名列表不同：os.walk() 只产生文件路径os.path.walk()    产生目录树下的目录路径和文件路径"""
