def gZipFile(src, dst):

in2out(fin, fout)
def gunZipFile(gzFile, dst):

src = r'D:\tmp\src.txt'

ori = r'D:\tmp\ori.txt'
gZipFile(src, dst)
print('gZipFile over!')
gunZipFile(dst, ori)
print('gunZipFile over!')也可以简单地封装成一个类：
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()相关阅读：
