程序输出的行数比它应该的多

Question

我一直在尝试写一个程序，读取行，每行它应该返回一个字母。不幸的是，问题在于输出中的行数比输入中的行数多（160k行输入中约有20行）

如果有人能告诉我我做错了什么，我会非常高兴的

#!/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")

正如用户tdelaney所说： 您使用的是python的通用换行符模式“rU”，它可能会生成与其他程序不同的行数，尤其是在文件中有一个未附加的“\r”时。完成for循环后，执行print repr（filein.newlines）。如果有问题，那就是您的问题。”
