Python压缩和解压缩zip文件

zip文件是我们经常使用的打包格式之一，python解压和压缩zip效率非凡。 python解压zip文档：

#/usr/bin/python

#coding=utf-8
import os,sys,time

import zipfile
filename = 'callofdutyblackopszombies_1349649132343_my.zip'  #要解压的文件

filedir = 'data/'  #解压后放入的目录

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归档中目录

        fz.extract(file,filedir)

    endtime = time.time()

    times = endtime - starttime

else:

    print('This file is not zip file')

print('times' + str(times))

python压缩文件夹为zip

#/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/'  #要进行压缩的文档目录

start = path.rfind(os.sep) + 1

filename = 'callofdutyblackopszombies_1349649132343_my.zip'  #压缩后的文件名
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()
