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()
