即使用笔，如何阻止乌龟画画? [英] How to stop turtle from drawing even with pen up?

问题描述

我在 python 中使用了turtle模块.问题是，每当我让乌龟移动时，即使笔在上面，我也会画画.例如，如果我运行这个程序:

I am using the turtle module in python. the problem is that whenever I have the turtle move i will draw even if the pen is up. for example if I run this program:

import turtle

turtle.penup
turtle.goto(0,50)

海龟移动到 (0,50) 时仍然会画一条线为什么会这样，如何预防?

the turtle will still draw a line when it moves to (0,50) why is this and how can it be prevented?

推荐答案

看起来您实际上并没有调用turtle.penup.试试这个:

It looks like you're not actually calling turtle.penup. Try this:

import turtle

turtle.penup()
turtle.goto(0,50)
