请用python写一个画爱心代码

以下是Python画爱心的代码：

import turtle

# 设置画布大小
canvas = turtle.Screen()
canvas.setup(width=400, height=400)

# 设置画笔
pen = turtle.Turtle()
pen.hideturtle()
pen.speed(0)
pen.pensize(3)

# 画红色爱心
pen.color('red')
pen.fillcolor('red')
pen.begin_fill()
pen.left(45)
pen.forward(100)
pen.circle(50, 180)
pen.right(90)
pen.circle(50, 180)
pen.forward(100)
pen.end_fill()

# 画白色爱心
pen.color('white')
pen.fillcolor('white')
pen.begin_fill()
pen.left(45)
pen.forward(70)
pen.circle(25, 180)
pen.right(90)
pen.circle(25, 180)
pen.forward(70)
pen.end_fill()

# 显示结果
turtle.done()

运行代码后，会在画布上画出一个红色和白色相间的爱心。
