zip文件是我們經常使用的打包格式之一，python解壓和壓縮zip效率非凡。 python解壓zip文檔：

#/usr/bin/python
#coding=utf-8

import os,sys,time
import zipfile

filename = 'callofdutyblackopszombies_1349649132343_my.zip' #要解壓的文件
filedir = 'data/' #解壓后放入的目錄
r = zipfile.is_zipfile(filename)
if r:
    starttime = time.time()
    fz = zipfile.ZipFile(filename,'r')
    for file in fz.namelist():
        print(file) #打印zip歸檔中目錄
        fz.extract(file,filedir)
    endtime = time.time()
    times = endtime - starttime
else:
    print('This file is not zip file')
print('times' + str(times))

python壓縮文件夾為zip

復制代碼代碼如下:

#/usr/bin/python
#coding=utf-8

import os
import zipfile
import sys

try:
    import zlib
    compression = zipfile.ZIP_DEFLATED
except:
    compression = zipfile.ZIP_STORED

path = 'data/' #要進行壓縮的文檔目錄
start = path.rfind(os.sep) + 1
filename = 'callofdutyblackopszombies_1349649132343_my.zip' #壓縮后的文件名

z = zipfile.ZipFile(filename,mode = "w",compression = compression)
try:
    for dirpath,dirs,files in os.walk(path):
        for file in files:
            if file == filename or file == "zip.py":
                continue
            print(file)
            z_path = os.path.join(dirpath,file)
            z.write(z_path,z_path[start:])
    z.close()
except:
    if z:
        z.close()
