Question

您好我是编程新手，我正在编写一个程序，要求用户输入颜色。然后程序将告诉用户该颜色是否是油漆，光线，两者或两者的主要颜色。

原色为红色，蓝色和黄色

光的基色是红色，蓝色和绿色。

到目前为止，这是我的代码：

a = input("Enter Colour: ")
if 'Yellow' in a:
 print('Yellow is a primary coulour for paint.')
elif 'Green' in a:
 print('Green is a primary colour for light.')
elif 'blue' in a:
 print('blue is a primary colour for light and paint.')
elif 'red' in a:
 print('red is a primary colour for light and paint')
else:
 print(a,'is not a primary colour.')

我使用此代码的问题是当我使用不同的情况时。例如，输入蓝色应提供与Blue或BLUe相同的输出。

所以我希望程序忽略这个案例。

任何事情都会有所帮助。

Answer 1

试试这个：

a = input("Enter Colour: ").lower()
if 'yellow' in a:
 print('Yellow is a primary coulour for paint.')
elif 'green' in a:
 print('Green is a primary colour for light.')
elif 'blue' in a:
 print('blue is a primary colour for light and paint.')
elif 'red' in a:
 print('red is a primary colour for light and paint')
else:
 print(a,'is not a primary colour.')

通过将输入转换为小写，您可以只检查颜色的小写版本。

Answer 2

尝试：

a = input("Enter Colour: ").strip()
color = a.lower()

if color in ["red", "blue"]:
    print(color, "is a primary colour for light and paint.")
elif color in ["yellow"]:
    print("Yellow is a primary colour for paint.")
elif color in ["green"]:
    print("Green is a primary colour for light.")
else:
    print(a, "is not a primary colour.")
