蟒蛇3石头剪刀布循环

Question

当我运行程序时：

R,S or P?
Rock
you threw : R
your enemy threw : R
>>>

最后一行代码不显示

if user_choice == computer_choice :
print ("tie!")

你知道我该怎么办吗？

谢谢！

import random

def main():
user_choice = input("R,S or P?n")
user_choice = user_choice.lower()
if user_choice == "rock" or user_choice == "r"  :
print("you got R")
elif user_choice == "p" or user_choice == "paper" :
print("you got  P")
elif user_choice == "s" or user_choice == "scissors" :
print("you got S")
else :
print ("wrong answer!")
computer_choice = random.randint(1,3)
if computer_choice == 1 :
print("your enemy chose  R")
elif computer_choice == 2 :
print("your enemy chose  P")
else :
print("your enemy chose S")

if user_choice == computer_choice :
print ("tie!")

main ()

Answer 1

更改自：

computer_choice = random.randint(1,3)
if computer_choice == 1 :
print("your enemy threw : R")
elif computer_choice == 2 :
print("your enemy threw : P")
else :
print("your enemy : S")
if user_choice == computer_choice :
print ("It's a tie!")

自：

computer_choice = random.randint(1,3)
if computer_choice == 1 :
computer_choice = 'r'
print("your enemy threw : R")
elif computer_choice == 2 :
computer_choice = 'p'
print("your enemy threw : P")
else :
computer_choice = 's'
print("your enemy : S")
if user_choice[0] == computer_choice :
print ("It's a tie!")

Answer 2

用户选择是字符串，计算机选择是整数，因此比较总是失败。
