本文实例讲述了Python判断文本中消息重复次数的方法。分享给大家供大家参考，具体如下：

#coding:gbk ''' Created on 2012-2-3 从文件中读取文本，并判断文本中形如“message0”、“message123”这样的消息有多少条是重复的 @author: Administrator ''' import re if __name__ == '__main__': pattern = u"(message((d)+))" prog = re.compile(pattern) # read text from file f = open("1003.txt","r") text = unicode(f.read()) f.close() result = prog.findall(text) message_map = dict() redupicate_count = 0 for message in result: if message_map.has_key(message[0]) == True: print message[0], "is reduplicate" redupicate_count += 1 else : message_map[message[0]] = 1; print "total reduplicate message is ", redupicate_count

希望本文所述对大家Python程序设计有所帮助。
