Question

我当时正在练习Python程序，然后又制作了剪刀，石头剪刀布程序。并且程序运行完美，但是问题是这样的：我选择了“摇滚，纸，剪刀”。但是，如果我以其他任何方式输入石头，纸张，剪刀，则会打印出其他陈述，即无效选择。我想使用大写/小写字母，但如何以及在何处使用。

import random

user = input("""Tell Me What Do You Choose:
        ~Rock
        ~Paper
        ~Scissors. 
        -> I Choose : """)
choose = ["Rock", "Paper", "Scissors"]
computer = random.choice(choose)
print(f"Computer Chose {computer}.")
#Function To Compare Choices
def compare(user, computer):
    if user == computer:
       return("It's A Tie :(....")
    elif user == "Rock":
         if computer == "Scissors":
             return("User Wins!")
         else:
             return("Computer Wins!")
    elif user == "Scissors":
         if computer == "Paper":
             return("User Wins!")
         else:
             return("Computer Wins!")
    elif user == "Paper":
         if computer == "Rock":
             return("User Wins!")
         else:
             return("Computer Wins!")

    else:
        return("User Choose Out Of The Options!")
        exit()
print(compare(user, computer))

Answer 1

只需使用lower() method

将您的输入转换为小写

user = user.lower()

将sCiSsOrS变成scissors 您还需要将if语句调整为全部小写

elif user == "Rock": --> elif user == "rock":
