雪飘落在对面的屋顶上，屋顶像蒙了一条闪着银光的纱巾，美丽极了。雪飘落在树上，树上像缀满了银色的小花。雪飘落在操场上，操场变得像铺满棉花一样白茫茫的一片。
本文实例讲述了python zip和unzip数据的方法。分享给大家供大家参考。具体实现方法如下：
# zipping and unzipping a string using the zlib module # a very large string could be zipped and saved to a file speeding up file writing time # and later reloaded and unzipped by another program speeding up reading of the file # tested with Python24 vegaseat 15aug2005 import zlib str1 = \ """Dallas Cowboys football practice at Valley Ranch was delayed on Wednesday for nearly two hours. One of the players, while on his way to the locker room happened to look down and notice a suspicious looking, unknown white powdery substance on the practice field. The coaching staff immediately suspended practice while the FBI was called in to investigate. After a complete field analysis, the FBI determined that the white substance unknown to the players was the goal line. Practice was resumed when FBI Special Agents decided that the team would not be likely to encounter the substance again. """ print '-'*70 # 70 dashes for the fun of it print str1 print '-'*70 crc_check1 = zlib.crc32(str1) print "crc before zip=", crc_check1 print "Length of original str1 =", len(str1) # zip compress the string zstr1 = zlib.compress(str1) print "Length of zipped str1 =", len(zstr1) filename = 'Dallas.zap' # write the zipped string to a file fout = open(filename, 'w') try: print >> fout, zstr1 except IOError: print "Failed to open file..." else: print "done writing", filename fout.close() # read the zip file back fin = open(filename, 'r') try: zstr2 = fin.read() except IOError: print "Failed to open file..." else: print "done reading", filename fin.close() # unzip the zipped string from the file str2 = zlib.decompress(zstr2) print '-'*70 print str2 print '-'*70 crc_check2 = zlib.crc32(str2) print "crc after unzip =", crc_check2, "(check sums should match)"
希望本文所述对大家的Python程序设计有所帮助。
以上就是python中zip和unzip数据的方法。食堂，寝室，教室，你就只能去这三个地方，拉屎吃饭都是时间在浪费，你应该学习！更多关于python中zip和unzip数据的方法请关注haodaima.com其它相关文章！
