python 移动文件，移动文件夹里的文件夹里的文件

import os
import shutil
path=r'F:/os'  # 原文件夹路径,还有文件夹
all=os.listdir(path)
all_path=[]
for i in all:
    all_path1=os.path.join('F:\os',i)
    all_path.append(all_path1)

newpath = r'F:/all'  # 目的文件夹路径  
def listMyDir(param):
    pass
def writeFile(param):
    pass
for absolute_path in all_path:

    for dirpath,dirnames,filenames in os.walk(absolute_path):     #遍历目录
            if dirnames:
                for dirname in dirnames:
                    listMyDir(os.path.join(dirpath, dirname))
            if filenames:
                for filename in filenames:
                    writeFile(os.path.join(dirpath,filename))
                    file_name = '{0}/{1}'.format(dirpath, filename)    #拼接形成文件路径
                    shutil.move(file_name, newpath)                     #批量移动文件到新文件夹

print('end')
