How to compress and decompress gzip files in Python

This article describes how to compress and decompress gzip files in Python. it analyzes how to compress a gzip file into a gzip file and decompress a gzip file, and provides corresponding encapsulation classes, for more information about how to compress and decompress gzip files in Python, see the following example. We will share this with you for your reference. The details are as follows:

# Encoding = UTF-8 # author: walker # date: 2015-10-26 # summary: test gzip compression/decompression file import gzipBufSize = 1024 * 8def gZipFile (src, dst): fin = open (src, 'RB') fout = gzip. open (dst, 'wb') in2out (fin, fout) def gunZipFile (gzFile, dst): fin = gzip. open (gzFile, 'RB') fout = open (dst, 'wb') in2out (fin, fout) def in2out (fin, fout): while True: buf = fin. read (BufSize) if len (buf) <1: break fout. write (buf) fin. close () fout . Close () if _ name _ = '_ main _': src = R'D: \ tmp \ src.txt 'dst = R'D: \ tmp \ src.txt.gz 'ori = R'D: \ tmp \ ori.txt 'gzipfile (src, dst) print ('gzipfile over! ') GunZipFile (dst, ori) print ('gunzipfile over! ')

It can also be simply encapsulated into a class:

class GZipTool:  def __init__(self, bufSize):    self.bufSize = bufSize    self.fin = None    self.fout = None  def compress(self, src, dst):    self.fin = open(src, 'rb')    self.fout = gzip.open(dst, 'wb')    self.__in2out()  def decompress(self, gzFile, dst):    self.fin = gzip.open(gzFile, 'rb')    self.fout = open(dst, 'wb')    self.__in2out()  def __in2out(self,):    while True:      buf = self.fin.read(self.bufSize)      if len(buf) < 1:        break      self.fout.write(buf)    self.fin.close()    self.fout.close()
