Python 遍历文件夹及子文件夹

在游戏公司搞SDK，需要搞混淆（你懂的），闲来无事研究Python..
Mark第一步
方法一：

#!/usr/bin/env python3
# coding:utf-8

import os

_defaultList = [".h",".m"]

def list_all_files(path):

    if not os.path.isdir(path) and not os.path.isfile(path):
        return False

#只要.h，.m文件
# if os.path.isfile(path) and os.path.splitext(path)[-1] in _defaultList and os.path.splitext(os.path.basename(path))[0] not in _files: 
    if os.path.isfile(path) : #文件
        print(path)
    elif os.path.isdir(path): #文件夹
        for i in os.listdir(path): #递归
            list_all_files(os.path.join(path,i))
    return True

def list_all_files_do_something(path):
    if list_all_files(path) == True:
        print(_files)
        #下一步操作
    else:
        print("非法")

if __name__ == '__main__':
    path = "/文件夹路径"
    list_all_files_do_something(path)

方法二：

_files = []
_defaultList = [".h",".m"]
def list_all_files(path):
    if not os.path.isdir(path) and not os.path.isfile(path):
        # print("非法")
        return False

    for root, dirs, files in os.walk(path):
        for name in dirs: #目录
            print("dirs",os.path.join(root, name))
        for name in files: #文件
            print("dirs",os.path.join(root, name))

    return True

def list_all_files_do_something(path):
    if list_all_files(path):
        print(_files)
    else:
        print("非法")

if __name__ == '__main__':
    path = "/文件夹路径"
    list_all_files_do_something(path)
