源代码

import turtle

# 设置画布大小
turtle.setup(600, 600)

# 设置画笔粗细
turtle.pensize(3)

# 绘制横坐标和纵坐标
turtle.penup()
turtle.goto(-300, 0)
turtle.pendown()
turtle.forward(600)
turtle.penup()
turtle.goto(0, -300)
turtle.pendown()
turtle.left(90)
turtle.forward(600)
turtle.right(90)

# 绘制四个圆形
colors = ['green', 'yellow', 'blue', 'red']
coord = [(0, 70), (100, -100), (0, -270), (-100, -100)]
for i in range(4):
  turtle.penup()
  turtle.goto(coord[i])
  turtle.pendown()
  turtle.fillcolor(colors[i])
  turtle.begin_fill()
  turtle.circle(100)
  turtle.end_fill()

turtle.done()
