「Python绘图」绘制太极图

python 绘制太极

一、预期结果

二、核心代码

import turtle

pen = turtle.Turtle()

print("开始绘制太极")

radius = 100
pen.color("black", "black")
pen.begin_fill()
pen.circle(radius/2, 180)
pen.circle(radius, 180)
pen.left(180)
pen.circle(-radius/2, 180)
pen.end_fill() 


pen.left(90)
pen.pu()
pen.fd(radius*0.35)
pen.right(90)
pen.pd()

print("绘制小圆")
pen.color("white", "white")
pen.begin_fill()
pen.circle(radius*0.15)
pen.end_fill() 


pen.left(90)
pen.up()
pen.backward(radius*0.7)
pen.down()
pen.left(90)

print("绘制小圆")
pen.color("black", "black")
pen.begin_fill()
pen.circle(radius*0.15)
pen.end_fill()

print("补大圆")
pen.right(90)
pen.pu()
pen.backward(radius*0.65)
pen.right(90)
pen.pd()
pen.circle(radius, 180)
print("绘制完成")
pen.ht()
turtle.done()
