如何填充两个圆的相交区域的另一种颜色？

import turtle

# 创建两个圆形对象
circle1 = turtle.Turtle()
circle2 = turtle.Turtle()

# 设置圆形对象的位置、半径和颜色
circle1.penup()
circle1.goto(-50, 0)
circle1.pendown()
circle1.color("blue")
circle1.circle(50)

circle2.penup()
circle2.goto(50, 0)
circle2.pendown()
circle2.color("green")
circle2.circle(50)

# 计算两个圆的相交区域
intersection_area = 50 * 50 * 3.1415 / 2

# 填充相交区域的颜色
turtle.begin_fill()
turtle.fillcolor("red")
turtle.circle(50)
turtle.end_fill()

turtle.done()
