Simple tutorial for compressing files using the gzip module in Python-Python tutorial

This article describes how to use the gzip module to compress files in Python. the examples in this article are mainly for UNIXZ systems. For more information, see Create a gzip file with compressed data
First look at a slightly troublesome practice

Import StringIO, gzipcontent = 'Life is short. I use python 'zbuf = StringIO. stringIO () zfile = gzip. gzipFile (mode = 'WB ', compresslevel = 9, fileobj = zbuf) zfile. write (content) zfile. close ()

However, there is a fast encapsulation, and the StringIO module is not used.

F = gzip.open('file.gz ', 'wb') f. write (content) f. close ()

Compress existing files
After python2.7, you can use the with statement.

Import gzipwith open ("/path/to/file", 'RB') as plain_file: with gzip. open ("/path/to/file.gz", 'wb') as zip_file: zip_file.writelines (plain_file)

If you do not consider cross-platform, only on the linux platform, the following method is more direct:

From subprocess import check_callcheck_call ('gzip/path/to/file', shell = True)
