如何在Python的“Turtle”库中找到点的坐标？

Question

我想使用 python 的 Turtle 库制作一个形状，为此，我必须找到形状中心的坐标，然后使用

goto()

命令。这样可以吗？

而且我也尝试通过移动乌龟而不是使用

goto()

命令来到达中心，但这是不可能的，或者我做错了什么。一些帮助将非常感激！

可以分享一下你的代码吗？

1. 如果您想在屏幕上找到海龟形状的当前位置，请使用 turtle.pos()

from turtle import Turtle, Screen
import random as rnd

screen = Screen()
my_shape = Turtle(shape='turtle')
my_shape.penup()
my_shape.goto(x=rnd.randint(1, 50), y=rnd.randint(1, 50))  # send turtle to random position ve+ x and ve+ y coordinate
curr_pos = my_shape.pos()  # get current turtle position by turtle.pos() method
print(f"current position: {curr_pos}")
screen.exitonclick()

输出-->

current position: (45.00,5.00)

2. 如果您尝试在中央屏幕中恢复形状，请使用 turtle.home()

from turtle import Turtle, Screen
import random as rnd

screen = Screen()
my_shape = Turtle(shape='turtle')
my_shape.penup()
my_shape.goto(x=rnd.randint(1, 50), y=rnd.randint(1, 50))  # send turtle to random position ve+ x and ve+ y coordinate
curr_pos = my_shape.pos()  # get current turtle position by turtle.pos() method
print(f"current position: {curr_pos}")
my_shape.home()  # send turtle to home position (0,0)
home_pos = my_shape.pos()
print(f"Home position: {home_pos}")
screen.exitonclick()

输出-->

current position: (48.00,41.00) Home position: (0.00,0.00)
