Question

嗨，这是学校的工作，所以请不要给我正确的答案，但告诉我我做错了所以我可以去纠正它。所以我的代码工作正常，但有一个问题。当我键入＆＃34; Coin＆＃34;时，显示硬币翻转后会显示错误消息。这是我的代码：

def program():
    error_message = "Answer not recognised!\nMake sure it is spelt right and starts with a capital letter."
    Choice = input("Pick either 'Card' or 'Coin' ")
    if Choice == "Coin":
        import random

        r = random.randint(1,2)
        if r == 1:
            print ("Heads!")
        else:
            print ("Tails!")

    if Choice == "Card":
        import random
        card_number = random.randint(1,13)

        if card_number == 1:
            card_number = "Ace"
        elif card_number == 11:
            card_number = "Jack"
        elif card_number == 12:
            card_number = "Queen"
        elif card_number == 13:

            card_number = "King"

    if Choice == "Card":
        import random
        card_suit = random.randint(1,4)

        if card_suit == 1:
            card_suit = "Hearts"
        elif card_suit == 2:
            card_suit = "Clubs"
        elif card_suit == 3:
            card_suit = "Diamonds"
        else:
            card_suit = "Spades"

    if Choice == "Card":
        print(card_number ,"of" , card_suit)

    #else print error message
    else:
        print(error_message)


while flag:
    program()
    flag = input('Would you like to run the program again? [yes/no] ') == 'yes'

else:
    print ("The program will now terminate.")

我尝试了许多尝试解决这个问题的不同方法，但我无法弄明白。记住这是学校的工作，所以我想帮助，但不要被告知答案。感谢

在program()的最外层，您有四个单独的if语句。每个人将一个接一个地执行。 else附加到最终if。

if Choice == "Card":
    print(card_number ,"of" , card_suit)

#else print error message
else:
    print(error_message)

当Choice为Coin时，Choice == "Card"评估为false，因此选择了else分支。你的意思是有一个if这样的语句：

def program():
    error_message = ...
    Choice = ...
    if Choice == "Coin":
        # do all the coin related work
    elif Choice == "Card":
        # do all the card related work
    else:
        # handle the error

顺便说一句，它只是作为模块中的第一个代码，在风格上优于import模块。

谢谢大家我的代码现在正在运行，我现在只是想缩短它。谢谢这是完成的代码：

import random
flag = True
def program():
    error_message = "Answer not recognised!\nMake sure it is spelt right and starts with a capital letter."
    Choice = input("Pick either 'Card' or 'Coin' : ")

    if Choice == "Coin":
        r = random.randint(1,2)
        if r == 1:
            print ("Heads!")
        else:
            print ("Tails!")

    elif Choice == "Card":
        card_number = random.randint(1,13)

        if card_number == 1:
            card_number = "Ace"
        elif card_number == 11:
            card_number = "Jack"
        elif card_number == 12:
            card_number = "Queen"
        elif card_number == 13:
            card_number = "King"

        card_suit = random.randint(1,4)

        if card_suit == 1:
            card_suit = "Hearts"
        elif card_suit == 2:
            card_suit = "Clubs"
        elif card_suit == 3:
            card_suit = "Diamonds"
        else:
            card_suit = "Spades"

        print(card_number ,"of" , card_suit)

    else:
        print(error_message)


while flag:
    program()
    flag = input('Would you like to run the program again? [yes/no] ') == 'yes'

else:
    print ("The program will now terminate.")

我知道它的凌乱，但它现在有效，所以现在我将专注于缩短它并整理它。谢谢
