1、安装和导入turtle模块 turtle模块是Python内置的标准库,不需要额外安装。直接在Python代码中导入即可: import turtle 2、设置绘制环境 创建一个turtle对象并设置绘图的初始参数: wn = turtle.Screen() wn.title("Hexagon using Turtle") wn.bgcolor("white") hexagon = turtle.Turtle() hexagon.color("blue") ...
ani = animation.FuncAnimation(fig, animate, frames=360, interval=20, blit=True) plt.show() 2. 用户交互 通过Turtle库,用户可以实现交互式绘图。例如,可以让用户通过键盘输入来控制菱形的大小或旋转角度: def draw_diamond(size): for _ in range(2): turtle.forward(size) turtle.left(90) turtle.forwa...
The matplotlib.animation module serves as the primary tool, offering an object-oriented interface for creating frame-by-frame and function-based animations. Key animation libraries in Python include: LibraryPrimary Use CaseKey Features Matplotlib Animation Scientific visualization Real-time plotting, export...
简介:Python turtle库如何瞬间完成作图?难道只难像海龟一样慢慢爬吗? LOGO语言简介 20世纪60年代,美国麻省理工学院人工智能实验室的西摩尔·帕伯特专为孩子们设计了一种叫LOGO的计算机语言,是一种易学、易懂、易于掌握的结构化程序设计语言,出发点是将原本较为枯燥的程序设计形象化,希望学生不要机械地记忆事实,使学生...
turtle.towards(x, y=None) 参数 x – 一个数值或数值对/矢量,或一个海龟实例 y – 一个数值——如果 x 是一个数值,否则为 None 返回从海龟位置到由 (x,y)、矢量或另一海龟所确定位置的连线的夹角。 此数值依赖于海龟的初始朝向,这又取决于 “standard”/“world” 或“logo” 模式设置。 import turt...
