未正确调用较大主函数中的打印语句，并且未显示预期的输出

Question

我有一个石头剪刀布程序，它可以按照需要的方式运行，但有一个小错误。输出应该说明玩家选择了什么，计算机选择了什么，然后谁赢了。如果玩家选择石头，电脑选择纸，输出应该是：

你选择了摇滚。电脑选择了剪刀。石头打碎剪刀。玩家获胜！

我以为我在正确的函数中添加了最后一句，但是当我运行程序时，它并没有按预期打印出来。

import random

# Function: Display Menu
# Input: none
# Output: none
# displays the game rules to the user

# Input: two integers--one representing the computer's choice and the other representing the player's choice

# Call Main
main()

Answer 1

您以错误的顺序传递参数。您的函数签名需要 computerChoice 作为其第一个参数：

def playRound(computerChoice, playerChoice):

因此更改以下行：

result =  playRound(p_choice, c_choice)

到

result =  playRound(c_choice, p_choice)
