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()
