用Python代码实现爱心绘图

以下是Python代码实现爱心绘图的示例：

import turtle

# 设置画笔
pen = turtle.Turtle()
pen.penup()
pen.pensize(5)
pen.speed(0)

# 绘制爱心
def draw_heart():
    pen.goto(0,0)
    pen.pendown()
    pen.color('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()
    pen.right(135)
    pen.color('black')

# 绘制文字
def draw_text():
    pen.penup()
    pen.goto(0, -150)
    pen.write("I Love You", align='center', font=("Arial", 40, "normal"))

# 绘制爱心和文字
draw_heart()
draw_text()

# 隐藏画笔
pen.hideturtle()

# 等待用户关闭窗口
turtle.done()

运行代码后，将会在窗口中绘制出一个红色的爱心，并在爱心下方显示“I Love You”字样
