Question

我需要编写此代码，以便人在输入中输入颜色或风味，无论是大写还是小写。为此，我用不同的方式写了一个颜色的字符串。但是，无论我将颜色或味道设置为小写还是大写，它始终显示为错误。如何显示TRUE？

null

问题是您应该将所有颜色存储到list中，并且仅将and存储到这样的颜色中。而且您还应该从零开始学习如何定义类等

class class_apple:
    color = ""
    flavor = ""

Apple = class_apple()

Colors = ["Red", "red", "RED"]
Flavors = ["Sweet", "sweet", "SWEET"]

def Apple_color():
    Apple.color = input("Insert the color of the apple: ")
    if Apple.color in Colors:
        print("TRUE")
    else:
        print("FALSE")

但是我建议使用lower来字符串对象：

class class_apple:
    def __init__(self):
        self.color = ""
        self.flavor = ""

Apple = class_apple()

Colors = ["red", "green", "blue"]
Flavors = ["sweet", "spicy"]

def Apple_color():
    Apple.color = input("Insert the color of the apple: ")
    if Apple.color.lower() in Colors:
        print("TRUE")
    else:
        print("FALSE")

我不知道该怎么办
