python batch decompression compressed file example code

The following is an example code of python batch decompression compressed file, which is as follows;

#/usr/bin/python#coding=utf-8import os,sys 
import zipfile open_path='e:\\data'save_path='e:\\data' os.chdir(open_path)
# Go to the path 
# First, through zipfile Module opens at the specified location zip Documents 
# Pass in a list of file names, and the path where the list files are located, and the storage path def Decompression(files,file_path,save_path):  
os.getcwd()# Current path   os.chdir(file_path)# Go to the path   
for file_name in files:   
print(file_name)   
r = zipfile.is_zipfile(file_name)# Determine whether to extract the file    
if r:      
zpfd = zipfile.ZipFile(file_name)# Read compressed file      
os.chdir(save_path)# Go to storage path       
zpfd.extractall()      
zpfd.close()def files_save(open_path): 
for file_path,sub_dirs,files in os.walk(open_path):# Get all file names, paths    
print(file_path,sub_dirs,files)   
Decompression(files,file_path,save_path)files_save(open_path)
