Question

我的代码抛出一个错误，总结为：

“ Turtle中的颜色内置函数无法同时使用Python的内置函数和整数来确定颜色值时使用的不等式”

from turtle import *

pen = Turtle()
screen = Screen()
screen.colormode(255)
screen.bgcolor('white')

def pen_color(i):
    print("Input a number between 1 and 255 for red")
    red = input
    print("Input a number between 1 and 255 for green")
    green = input
    print("Input a number between 1 and 255 for blue")
    blue = input
    screen.bgcolor(red, green, blue)

pen_color(pen)
pen.exitonclick()

Answer 1

您的代码有几个问题：@PatrickHaugh指出：

print("Input a number between 1 and 255 for red")
red = input()

不会做您想要/期望的事情。要么做：

red = input("Input a number between 1 and 255 for red")

或更妙的是：

exitonclick()

接下来，这将无法工作，因为Screen是Turtle而非pen.exitonclick()的方法：

bgcolor()

最后，您遇到颜色问题的原因是screen.bgcolor(int(red), int(green), int(blue))需要数字参数，并且您将其传递给字符串。您需要这样做：

from turtle import Screen, Turtle

def pen_color():
    red = input("Input a number between 1 and 255 for red: ")
    green = input("Input a number between 1 and 255 for green: ")
    blue = input("Input a number between 1 and 255 for blue: ")

    screen.bgcolor(int(red), int(green), int(blue))

screen = Screen()
screen.colormode(255)

pen_color()

pen = Turtle()

screen.exitonclick()

将所有内容放在一起：

<Element Where="Time=3,Successful=N"></Element>

将RGB值输入到bgcolor（）时，Python乌龟引发错误
