从txt文件打印随机行？

Question

我使用random.randint生成一个随机数,然后将该数字赋给变量.然后我想用我分配给变量的数字打印行,但我一直收到错误:

列表索引超出范围

这是我试过的:

f = open(filename. txt)
lines = f.readlines() 

rand_line = random. randint(1,10)
print lines[rand_line]

Answer 1

你想用 random.choice

import random
with open(filename) as f:
    lines = f.readlines()
    print(random.choice(lines))
