在每次迭代中使用python在文本文件中写入换行符

希望在每次迭代中使用换行符，但它不起作用。我使用函数getUser（）和getFriends（）从abc.txt读取随机字符串。并写入文本文件new_file.txt，但每次迭代都会写入第一行

输出：['Larina']['Oormi'，'Palky']['Kavia']['Chakradhari'，'Chunni']

with open("new_file.txt", "wb") as sink:
        for i in range(0,2):
            print>>sink, getUser(),getFriends()
            #print>>sink,("\n")

def getUser():
    with open("abc.txt", "rb") as source:
        lines = [line.rstrip() for line in source]
    random_choice = random.sample(lines, 1)
    source.close()
    return(random_choice);
def getFriends():
    with open("abc.txt", "rb") as source:
        lines = source.read().splitlines()

    random_choice = random.sample(lines, 2)
    source.close()
    return(random_choice);

我需要以下格式：

[Larina][Oormi'，Palky']

['Kavia']['Chakradhari'，'Chunni']

with open("new_file.txt", "wb") as sink:
        for i in range(0,2):
            print>>sink, getUser(),getFriends()
            #print>>sink,("\n")

def getUser():
    with open("abc.txt", "rb") as source:
        lines = [line.rstrip() for line in source]
    random_choice = random.sample(lines, 1)
    source.close()
    return(random_choice);
def getFriends():
    with open("abc.txt", "rb") as source:
        lines = source.read().splitlines()

    random_choice = random.sample(lines, 2)
    source.close()
    return(random_choice);

您不必关闭

source

，因为

with

语句为您完成了这项工作

请尝试以下代码：

with open("new_file.txt", "wb") as sink:
        for i in range(0,2):
            sink.write("%s %s\n" % (str(getUser()), str(getFriends())))

def getUser():
    with open("abc.txt", "rb") as source:
        lines = [line.rstrip() for line in source]
    random_choice = random.sample(lines, 1)
    return(random_choice);

def getFriends():
    with open("abc.txt", "rb") as source:
        lines = source.read().splitlines()
    random_choice = random.sample(lines, 2)
    return(random_choice)

语句会按原样添加换行符。可能您使用的是一个错误的文本编辑器，它无法将

识别为换行符，并且期望
