程序的输出比它应该有更多的行

Question

我一直在尝试编写一个读取行的程序，每行都应该返回单个字母。不幸的是问题是在输出中有比输入更多的行（160k输入行大约20行）。

如果有人能告诉我我做错了什么，我会非常高兴。

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from collections import Counter
from re import split
import re
from itertools import islice
import random

def checkisin(femalewords, malewords, testin):
    with open(femalewords) as filein:
        femalewordslist = filein.readlines()
    with open(malewords) as filein:
        malewordslist = filein.readlines()

    letters = "FM"

    with open(testin, "rU") as filein:
        for line in filein:
            malecounter = 0
            femalecounter = 0
            linia = line.rstrip()
            if any(word in linia for word in femalewordslist):
                femalecounter = femalecounter+1
            if any(word in linia for word in malewordslist):
                malecounter = malecounter+1
            if malecounter > femalecounter:
                print "M"
            elif malecounter < femalecounter:
                print "F"
            elif malecounter == femalecounter:
                print random.choice(letters)

checkisin("femaletopwords.txt", "maletopwords.txt", "in2.tsv")

用户tdelaney说： ＆＃34;你正在使用python的通用换行模式＆＃34; rU＆＃34;这可能会产生与其他程序不同的行数，特别是如果有一个未连接的＆＃34; \ r＆＃34;在文件中。完成for循环后，执行print repr（filein.newlines）。如果它得到\ r \ n，那就是你的问题。＆＃34;
