Python compresses and decompress the zip file,

Zip files are one of the most frequently used packaging formats. It is extremely efficient to decompress and compress zip files in python. Decompress the zip file in python:
Copy codeThe Code is as follows:
#/Usr/bin/python
# Coding = UTF-8

Import OS, sys, time
Import zipfile

Filename = 'callofdutyblackopszombies_1349649132343_my.zip '# file to be decompressed
Filedir = 'data/'# directory to which the package is extracted
R = zipfile. is_zipfile (filename)
If r:
Starttime = time. time ()
Fz = zipfile. ZipFile (filename, 'R ')
For file in fz. namelist ():
Print (file) # print the directory in the zip Archive
Fz. extract (file, filedir)
Endtime = time. time ()
Times = endtime-starttime
Else:
Print ('this file is not zip file ')
Print ('times '+ str (times ))

The compressed python folder is zip.
Copy codeThe Code is as follows:
#/Usr/bin/python
# Coding = UTF-8

Import OS
Import zipfile
Import sys

Try:
Import zlib
Compression = zipfile. ZIP_DEFLATED
Except t:
Compression = zipfile. ZIP_STORED

Path = 'data/'# directory of the document to be compressed
Start = path. rfind (OS. sep) + 1
Filename = 'callofdutyblackopszombies_1349649132343_my.zip '# compressed file name

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 t:
If z:
Z. close ()
