TypeError：create_purple（）需要0个位置参数，但有2个被给出

Question

我是Python编程的新手，并试图使这个程序工作。

我已经通过使用“if”和“else”语句使这个程序工作，但是，我想用下面的方法制作这个程序。当我运行程序时，我不断收到一个错误“TypeError：create_purple（）需要0个位置参数，但2个给出”，我不明白为什么。

这里是我的代码：

#******************************************************************************************* 
# 
# This program will take any two primary colors and create a secondary color. 
# 
# Primary colors are: 
# Blue, Red, Yellow 
# 
# Secondary colors are: 
# Green, Orange, Purple 
# 

#Clear the screen 
import os 
os.system('cls') 

RED = "red" 
BLUE = "blue" 
YELLOW = "yellow" 

def main(): 
    print ('\n') 
    # Tell the user the objective of the program. 
    print ('*****************************************************************************') 
    print ('*****************************************************************************') 
    print ('\n') 
    print ('The objective of this program is to create a secondary color from two primary') 
    print ('colors. When asked, choose two primary colors (Red, Blue, or Yellow) to create') 
    print ('a secondary color ') 

    # Choose your colors 
    color1 = input('Enter your first primary color: ') 
    color2 = input('Enter your second primary color: ') 

    # Determine the secondary color 
    if color1 == RED and color2 == BLUE: 
    create_purple(color1,color2) 


def create_purple(): 

    # Determine the color is purple 
    if color1 == RED and color2 == BLUE: 
     print ('\n') 
     print ('You have made the color.... Purple ') 
    else: 
     if color1 == BLUE and color2 == RED: 
      print ('\n') 
      print ('You have made the color.... Purple ') 

# Call the main function 
main()

要调用以2个参数create_purple，但你的定义（DEF）有0参数。

简单地更新定义：

def create_purple(color1,color2):
