Question

我是Python编程的新手，并试图让这个程序工作。

我已经使用＆＃34;使这个程序工作了。如果＆＃34;和＆＃34;否则＆＃34;但是，我想用以下方法制作相同的程序。当我运行程序时，我不断收到错误＆＃34; TypeError：create_purple（）接受0个位置参数但是2个被给出＆＃34;我无法弄清楚原因。

这是我的代码：

#*******************************************************************************************
#
# 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()

Answer 1

您正在调用带有2个参数的create_purple，但您的定义（def）有0个参数。

只需更新定义：

def create_purple(color1,color2):

TypeError：create_purple（）接受0个位置参数，但给出了2个
