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() |
希望本文所述对大家Python程序设计有所帮助。
