Python's method of compressing and decompressing gzip large files _python

This article describes the Python implementation of compression and decompression of the gzip large file method. Share to everyone for your reference, specific as follows:

import gzip
bufsize = 1024*8
def 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! ')

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 ()
