运行软件：pycharm

画一个爱心的代码：

import turtle
def print_love1():
    # 设置画笔颜色和粗细
    turtle.pencolor("red")
    turtle.pensize(6)
    # 绘制爱心
    turtle.fillcolor("pink")
    turtle.begin_fill()
    turtle.left(45)
    turtle.forward(100)
    turtle.circle(50, 180)
    turtle.right(90)
    turtle.circle(50, 180)
    turtle.forward(100)
    turtle.end_fill()
    # 隐藏画笔
    turtle.hideturtle()
    # 显示结果
    turtle.done()

if __name__ == '__main__':
    print_love1()

循环画一个爱心的代码：

import turtle
import time

def print_love():
    # 设置画笔颜色和粗细
    turtle.pencolor("red")  # 或者使用 (135/255, 206/255, 235/255)
    turtle.pensize(6)
    # 绘制爱心
    turtle.fillcolor("pink")
    turtle.begin_fill()
    turtle.left(45)
    turtle.forward(100)
    turtle.circle(50, 180)
    turtle.right(90)
    turtle.circle(50, 180)
    turtle.forward(100)
    turtle.end_fill()

if __name__ == '__main__':
    turtle.speed(1)  # 设置绘制速度
    for _ in range(10):  # 循环绘制10个爱心
        print_love()
        time.sleep(1)  # 等待1秒以便观察
        turtle.clear()  # 清空画布
        turtle.penup()  # 抬起画笔
        turtle.goto(0, 0)  # 回到原点
        turtle.setheading(0)  # 重置方向
        turtle.pendown()  # 放下画笔
    turtle.hideturtle()  # 隐藏画笔
    turtle.done()  # 显示结果
