python 列表 元素 选取

def text_furface_get():

    text =[memeda','wtf','hello','vaseline','fuckthatbitch','this is a new world','we are the champion']
    x = N.random.randint(0,len(text) - 1)

    return text[x]



报错：an integer is required (got type tuple)

本来是希望通过用这个函数获取一个字符串的，但是获取text[x]后报错说是一个元组
请问这是怎么回事？要怎么修改才能获取text里面的字符串？

import random

def text_furface_get():

    text =['memeda','wtf','hello','vaseline','fuckthatbitch','this is a new world','we are the champion']
    x = random.randint(0,len(text) - 1)

    return text[x]

if __name__ == '__main__':
    print(text_furface_get())

random前面的N是什么意思？
