python表白代码画爱心树

好的，以下是一个简单的 Python 代码，可以画出一个爱心树：

import math

def draw_heart(x, y):
    # 画心形的函数
    points = []
    for i in range(0, 360):
        radians = math.radians(i)
        x = 16 * math.pow(math.sin(radians), 3)
        y = 13 * math.cos(radians) - 5 * math.cos(2 * radians) - 2 * math.cos(3 * radians) - math.cos(4 * radians)
        points.append((x, -y))
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.color('red')
    turtle.begin_fill()
    for point in points:
        turtle.goto(x + point[0], y + point[1])
    turtle.end_fill()

def draw_tree(x, y, length, angle):
    # 画树的函数
    if length < 10:
        return
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.setheading(angle)
    turtle.color('green')
    turtle.pensize(length / 20)
    turtle.forward(length)
    draw_tree(turtle.xcor(), turtle.ycor(), length * 0.7, angle + 30)
    draw_tree(turtle.xcor(), turtle.ycor(), length * 0.7, angle - 50)
    draw_heart(turtle.xcor(), turtle.ycor())
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.setheading(angle)
    turtle.color('brown')
    turtle.pensize(length / 10)
    turtle.backward(length * 0.1)

# 主函数
import turtle
turtle.speed(0)
turtle.hideturtle()
turtle.bgcolor('black')
turtle.penup()
turtle.goto(0, -200)
turtle.pendown()
turtle.color('white')
turtle.write("I love you", align="center", font=("Courier", 48, "bold"))
draw_tree(0, -100, 200, 90)
turtle.done()

将代码保存为 `love_tree.py`，然后在命令行中运行 `python love_tree.py`，就可以看到爱心树的画面了。
