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!')

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()
