Question

我在这里有一个更大的程序的一部分：

from random import randint

def computerChooses():
    import random
    choices = ["rock", "paper", "scissors"]
    computerChoice = choices[randint(0,2)]




def whoWins():
    if computerChoice == "rock":
                print("DO THIS")
    elif computerChoice == "paper":
                print("DO THIS")
    elif computerChoice == "scissors":
                print("DO THIS")

computerChooses()
whoWins()

我总是以：

NameError: name 'computerChoice' is not defined

（即使我相信是这样！）

错误消息指出，这是针对第20行和第12行的。

我在哪里做错了，特别是在哪里？

谢谢， hy

Answer 1

from random import randint

def computerChooses():
    import random
    choices = ["rock", "paper", "scissors"]
    computerChoice = choices[randint(0,2)]

    return computerChoice




def whoWins(computerChoice):
    if computerChoice == "rock":
            print("DO THIS")
    elif computerChoice == "paper":
            print("DO THIS")
    elif computerChoice == "scissors":
            print("DO THIS")

result = computerChooses()
whoWins(result)

在单独的函数中，即使没有定义，名称也未定义
