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
