用递归方法遍历目录：

使用到os模块，所以要先引入os模块

处理文件：

    核心是判断文件是否是目录文件，如果是目录文件就进行递归处理，直接将文件名打印出来

下面是文件代码：

import os
def getAllDir(path, sp = " "):
    fileList = os.listdir(path)
    #处理每一个文件
    sp += "    "
    for fileName in fileList:
        #判断是否是路径(用绝对路径)
        absFliePath = os.path.join(path, fileName)
        if os.path.isdir(absFliePath):
            print(sp + "目录：", fileName)
            #递归调用
            getAllDir(absFliePath, sp)
        else:
            print(sp + "普通文件", fileName)
    return fileList
getAllDir(r"C:\Users\Administrator\PycharmProjects\untitled\day011")

栈方法：

import os
def getAllDirDE(path):
    stack = []
    stack.append(path)
    #处理栈，当栈为空的时候结束循环
    while len(stack) != 0:
        dirPath = stack.pop()
        fileDir = os.listdir(dirPath)
        for fileName in fileDir:
            fileAbsPath = os.path.join(dirPath, fileName)
            if os.path.isdir(fileAbsPath):
                print("目录："+ fileName)
                stack.append(fileAbsPath)
            else:
                print("普通文件：", fileName)
getAllDirDE(r"C:\Users\Administrator\PycharmProjects\untitled\day011")

队列方法：

import os
import collections
def getAllDir(path):
    queue = collections.deque()
    #进队
    queue.append(path)
    while len(queue) != 0:
        dirPath = queue.popleft()
        fileList = os.listdir(dirPath)
        for fileName in fileList:
            fileAbsPath = os.path.join(dirPath, fileName)
            if os.path.isdir(fileAbsPath):
                print("目录："+fileName)
                queue.append(fileAbsPath)
            else:
                print("文件："+fileName)

getAllDir(r"C:\Users\Administrator\PycharmProjects\untitled\day011")
