TypeError: unsupported operand type(s) for %: 'NoneType' and 'tuple' with random generator?

Question

TypeError: unsupported operand type(s) for %: 'NoneType' and 'tuple'

我需要引用或图像来代替 %s 打印，但似乎无法弄清楚如何？

#!/usr/bin/python
import random

if __name__=="__main__":

print("Content-type: text/html")
print()

    quotes=["The course of true love never did run smooth.", "Life every man     holds dear; but the dear man holds honor far more precious dear than life.",
"To thine own self be true, and it must follow, as the night the day, thou canst not then be false to any man.", "Poor and content is rich, and rich enough.",
"If you have tears, prepare to shed them now.", "Words without thoughts never to heaven go."]

Answer 1

您可能正在使用 python 3.X。您的代码适用于 python 2.X，但您需要按如下方式更改它：

而不是：

print (s) % (x, y)

试试这个：

print (s % (x, y))
