海龟代码不工作，显示pylint没有memb

Question

我相信我已经正确地编写了所有的代码，但是我不断地收到一条错误消息，例如（“模块‘turtle’没有‘reset’成员）

import turtle

color = input('Enter a color:')

while (color != "QUIT"):
    turtle.reset()
    turtle.pencolor(color)
    turtle.pensize(10)

n = int(input('Enter a number:'))

if n % 3 == 0 and n % 5 == 0:
    turtle.penup()
    turtle.setposition(x=0, y=150)
    turtle.pendown()
    drawU(turtle.Turtle)
    turtle.penup()
    turtle.setposition(x = 0, y = -10)
    turtle.pendown()
    drawH(t)
elif n % 3 == 0:
    turtle.penup()
    turtle.setposition(x=0, y=150)
    turtle.pendown()
    drawU(turtle.Turtle)
elif n % 5 == 0:
    turtle.penup()
    turtle.setposition(x=0, y=150)
    turtle.pendown()
    drawH(turtle.Turtle)
else:
    turtle.pencolor('black')



def drawU (t):
    turtle.setheading(270)
    turtle.forward(150)
    turtle.left(90)
    turtle.forward(75)
    turtle.left(90)
    turtle.forward(150)

每个“海龟”都显示为一个错误。我不太确定我做错了什么。我在结尾还包括了turtle.done（），这只是我代码的一半

i believe i have coded everything correctly

远非如此：循环的终止取决于color的值，它在循环过程中从不改变；您应该在这里传递一个turtle实例drawU(turtle.Turtle)，但是要传递一个turtle类；你的else子句毫无意义，实际上是一个不可操作的词；显示的缩进不起作用；缺少drawH()函数

下面是我试图重建您的预期代码，但我不能确定：

from turtle import Screen, Turtle

def drawU(turtle):
    turtle.setheading(270)
    turtle.forward(150)
    turtle.left(90)
    turtle.forward(75)
    turtle.left(90)
    turtle.forward(150)

def drawH(turtle):
    pass

color = input('Enter a color: ')

screen = Screen()
turtle = Turtle()

while color != "QUIT":

    n = int(input('Enter a number: '))

    turtle.reset()
    turtle.pencolor(color)
    turtle.pensize(10)

    if n % 3 == 0 and n % 5 == 0:
        turtle.penup()
        turtle.setposition(x=0, y=150)
        turtle.pendown()
        drawU(turtle)
        turtle.penup()
        turtle.setposition(x=0, y=10)
        turtle.pendown()
        drawH(turtle)
    elif n % 3 == 0:
        turtle.penup()
        turtle.setposition(x=0, y=150)
        turtle.pendown()
        drawU(turtle)
    elif n % 5 == 0:
        turtle.penup()
        turtle.setposition(x=0, y=150)
        turtle.pendown()
        drawH(turtle)

    color = input('Enter a color: ')

screen.mainloop()
