光譜中的隨機顏色

Question

嗨，我是編程新手，我正在編寫一個程序，要求用戶輸入顏色。然後程序會告訴用戶該顏色是否爲油漆，燈光或兩者的主要顏色。

原色是紅色，藍色和黃色

原色光爲紅色，藍色和綠色。

這是我到目前爲止的代碼：

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.') 

我這段代碼遇到的問題是，當我使用不同的情況。 例如輸入藍色應該給出與藍色或BLUe相同的輸出。

所以我想讓程序忽略這種情況。

任何事情都會有所幫助，謝謝。

Answer 1

嘗試：

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.") 

Answer 2

試試這個：

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.') 

由輸入轉換成小寫字母，您可以檢查只是顏色的小寫版本。
