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

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
