#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 reif __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
