python - if、if-else 和 elif 语句

Question

我知道如何执行 if 语句和 elif 语句，但在此特定代码中我不知道如何执行。我真正想做的是，当用户输入女性或男性以及温度时，它会根据选择的性别显示适合该天气的服装。谁能帮我？

def main():
    
    print("Welcome to Outfitters Boulevard!")
    print()
    print("Where your next vacation outfit is just around the corner.")
    print("================================================")
    
    name = input("What is your name?")
    gender = input("Are you male or female?")
    favoriteColor = input("What is your favorite color?")
    temp = int(input("What is the temperature like where you're going?"))
    
    print(name + ", you mentioned that you're a female, your favorite color is " + favoriteColor + ",")
    print("and you're going somewhere with " + str(temp) + " weather.")
    print("We've got just the outfit for you: ")
    
    if temp>84:
        print("The Perfect Hot Weather Outfit")
    elif 70 >=temp<= 84:
        print("The Perfect Warm Weather Outfit")
    elif 55>=temp<= 69:
        print("The Perfect Cool Weather Outfit")
    elif temp <55: 
        print("The Perfect Cold Weather Outfit")
    
main()

我已经编辑了您的代码以添加嵌套的 if 语句，并使其更加用户友好。我添加了您问的项目，并指导您如何编写其他项目:

def main():
    
    print("Welcome to Outfitters Boulevard!")
    print()
    print("Where your next vacation outfit is just around the corner.")
    print("================================================")
    
    name = input("What is your name?")
    gender = input("Are you male or female or other?")
    favoriteColor = input("What is your favorite color?")
    temp = int(input("What is the temperature like where you're going?"))
    
    print(name + ", you mentioned that you're a female, your favorite color is " + favoriteColor + ",")
    print("and you're going somewhere with " + str(temp) + " weather.")
    print("We've got just the outfit for you: ")
    
    if temp>84:
        print("The Perfect Hot Weather Outfit")
        if gender.casefold() == 'male':
            # Show male outfits here
            print("Hawaiian shirt, shorts and flip flops")

        elif gender.casefold() == 'female':
            # Show female outfits here
            print("Shorts, sandals and a crop shirt.")

        else:
            # Show other outfits here

    elif 70 >=temp<= 84:
        print("The Perfect Warm Weather Outfit")
        if gender.casefold() == 'male':
            # Show male outfits here

        elif gender.casefold() == 'female':
            # Show female outfits here

        else:
            # Show other outfits here

    elif 55>=temp<= 69:
        print("The Perfect Cool Weather Outfit")
        if gender.casefold() == 'male':
            # Show male outfits here

        elif gender.casefold() == 'female':
            # Show female outfits here

        else:
            # Show other outfits here

    elif temp <55: 
        print("The Perfect Cold Weather Outfit")
        if gender.casefold() == 'male':
            # Show male outfits here

        elif gender.casefold() == 'female':
            # Show female outfits here

        else:
            # Show other outfits here
    
main()

casefold()方法确保大写无关紧要，因此用户可以用不同的大写回答性别问题，并且仍然可以得到输出。
