写triangle()函数,函数功能为绘制给定变长的三角形。 等边三角形 多边形是有多个边的图形。等边三角形是多边形的一种,有三条边且变长相等。 ?...练习1-4:写绘制多边形的函数。函数名字为polygon,参数为一个整数,函数功能是绘制多边形,边的条数为参数值。...总结 本文我们学习了使用Python的小龟模块turtle和它...
默认有以下多边形形状:"arrow", "turtle", "circle", "square", "triangle", "classic"。设置成什么turtle就会变成什么形状。 代码示例: import turtle print(turtle.shape()) turtle.shape('turtle') 效果 resizemode() 使用语法: turtle.resizemode(rmode=None) 参数说明: rmode:字符串 "auto", "user"...
print("Please enter (x,y) of three points in turn: ") x1,y1=eval(input("Point1:(x,y)=")) x2,y2=eval(input("Point2:(x,y)=")) x3,y3=eval(input("Point3:(x,y)=")) if(isTriangle(x1,y1,x2,y2,x3,y3)): #计算三角形周长 ...
如果start_angle == stop_angle, 则不会绘制任何内容。 让我们考虑一个例子: import pygame from math import pi pygame.init() # size variable is using for set screen size size = [400, 300] screen = pygame.display.set_mode(size) pygame.display.set_caption("Example program to draw geometry")...
() function while passing in an integer value of 75. This tells the turtle to move 75 steps beginning from the middle of the canvas. A step is equivalent to a pixel. By default, the turtle is actually an arrow shape, and it moves to the right unless youchange turtle’s direction. ...

Write a Python program to calculate the arc length of an angle. Note: In a planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in a plane, but this plane...
海龟的形状初始时有以下几种:blank,arrow,turtle,circle,square,triangle,classic,其中字符串blank表示不使用任何形状,将会让海龟处于隐身状态。 (11)getshapes()获的海龟当前可设置的形状种类,其语法格式为: turtle.getshapes() 该方法用于返回所有当前可用海龟形状的列表。例如: ;案例:海龟的不同形状;在使用海龟...
