python 批量解压压缩文件的实例代码
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)
