Python标准库中有个turtle模块,俗称“海龟绘图”,它提供了一些简单的绘图工具,可用于在标准的应用程序窗口中绘制各种图形。海龟绘图方式非常简单、直观,就像有一只尾巴上蘸着颜料的小海龟在计算机屏幕上爬行,随着它的移动就能画出线条来。使用turtle模块,我们只用几行代码就能创建出令人印象深刻的视觉效果,还可以跟随海龟...
除了删除画笔的绘制之外,我们还可以使用pythonturtle库提供的reset()函数来清空画布。该函数会重置画布的状态,并将画笔移动到初始位置。下面是一个示例代码: importturtle# 创建画布和画笔canvas=turtle.Screen()pen=turtle.Turtle()# 绘制一个正方形for_inrange(4):pen.forward(100)pen.right(90)# 清空画布pen.re...
>>> import turtle >>> bob = turtle.Turtle() 上述代码运行后,应该会新建一个窗口,窗口中间有一个小箭头,代表的就是海龟。现在关闭窗口。 新建一个名叫mypolygon.py的文件,输入以下代码: import turtle bob = turtle.Turtle() print(bob) turtle.mainloop() turtle模块(小写的t)提供了一个叫作Turtle的函数...
Python Turtle is a built-in module in Python that allows users to create graphics and drawings using a turtle that can move around the screen. The turtle can be controlled with a set of simple commands such asforward(),backward(),left(), andright()to draw shapes and patterns on the scr...
