使用乌龟创建盒子

Question

谁能帮我制作几个盒子，每个盒子都在不同的坐标轴上使用 turtle，
P.S。尝试在以下代码中使用 class 和对象：

import turtle
from turtle import *

# window:
window = turtle.Screen()
window.bgcolor("white")
window.title("Process flow")


class a:
    penup()
    shape("square")
    speed(0)

    def __init__(self, reshape, color, location):
        self.reshape = reshape
        self.color = color
        self.location = location


start_node1 = a(reshape=shapesize(stretch_wid=1, stretch_len=3), color=color("light blue"), location=goto(0, 300))
start_node2 = a(reshape=shapesize(stretch_wid=1, stretch_len=3), color=color("yellow"), location=goto(0, 270))


print(start_node1)
print(start_node2)


done()

Answer 1

您似乎将随机的代码串在一起，希望它能起作用。例如。参数调用如：

..., location=goto(0, 300)

将 None 传递给您的初始化程序，因为这就是 goto() returns。并以两种不同的方式导入海龟：

import turtle
from turtle import *

表明您在概念上遇到了麻烦。以下是我对您的代码进行的修改，以在不同位置显示不同颜色和大小的框，以尽可能多地保留原始代码的“风味”：

from turtle import Screen, Turtle

class Box(Turtle):
    def __init__(self, reshape, color, location):
        super().__init__(shape='square', visible=False)

        self.shapesize(**reshape)
        self.color(color)
        self.speed('fastest')
        self.penup()
        self.goto(location)

        self.showturtle()

screen = Screen()
screen.title("Process flow")

start_node1 = Box(reshape={'stretch_wid':1, 'stretch_len':3}, color='light blue', location=(100, 300))
start_node2 = Box(reshape={'stretch_wid':2, 'stretch_len':4}, color='yellow', location=(-100, 270))

screen.exitonclick()
