python 批量解压压缩文件的实例代码_Python

下面给大家介绍python 批量解压压缩文件的实例代码，代码如下所述；

				?

									#/usr/bin/python#coding=utf-8import os,sys 

									import zipfile open_path='e:\\data'save_path='e:\\data' os.chdir(open_path)

									#转到路径

									#首先，通过zipfile模块打开指定位置zip文件

									#传入文件名列表，及列表文件所在路径，及存储路径def Decompression(files,file_path,save_path):  

									os.getcwd()#当前路径  os.chdir(file_path)#转到路径  

									for file_name in files:   

									print(file_name)   

									r = zipfile.is_zipfile(file_name)#判断是否解压文件   

									if r:      

									zpfd = zipfile.ZipFile(file_name)#读取压缩文件     

									os.chdir(save_path)#转到存储路径      

									zpfd.extractall()      

									zpfd.close()def files_save(open_path): 

									for file_path,sub_dirs,files in os.walk(open_path):#获取所有文件名，路径   

									print(file_path,sub_dirs,files)   

									Decompression(files,file_path,save_path)files_save(open_path)

在看下一段代码python批量解压

									# 下述三行是为了解决编码问题

									1. 代码第一部分，首先迭代给定的文件目录，取得需要处理的zip文件，存储在一个列表里面，为后边的文件处理服务。此处主要是使用os.walk来迭代目录，然后使用os.path.join连接两个目录。

									'''

									file_name_list = []

									for dirpath, dirnames, filenames in os.walk(file_path):

									  for file_name in filenames:

									    if file_name.endswith('.zip'):

									      temp_path = os.path.join(dirpath, file_name)

									      file_name_list.append(temp_path)

									'''

									2. 对获取到的上述文件，进行了排序使输出的顺序有序。

									'''     

									sorted(file_name_list)

									'''

									3. 正文部分

									'''
