python实现粉色爱心代码

以下是Python实现粉色爱心的代码：

from tkinter import *
from math import sin, cos

# 设置画布大小和中心点
CANVAS_WIDTH = 600
CANVAS_HEIGHT = 600
CANVAS_CENTER_X = CANVAS_WIDTH / 2
CANVAS_CENTER_Y = CANVAS_HEIGHT / 2

# 设置收缩率和放大倍数
IMAGE_ENLARGE = 20
SHRINK_RATIO = 0.02

# 定义爱心函数
def heart_function(t, shrink_ratio: float = IMAGE_ENLARGE):
    x = 16 * (sin(t) ** 3)
    y = -(13 * cos(t) - 5 * cos(2 * t) - 2 * cos(3 * t) - cos(4 * t))
    # 放大
    x *= shrink_ratio
    y *= shrink_ratio
    # 移到画布中央
    x += CANVAS_CENTER_X
    y += CANVAS_CENTER_Y
    return int(x), int(y)

# 绘制爱心
def draw_heart(root, canvas):
    # 设置画笔颜色和宽度
    canvas.config(bg='pink')
    canvas.create_line(heart_function(0), heart_function(0), fill='red', width=2)
    for t in range(1, 628):
        canvas.create_line(heart_function(t * SHRINK_RATIO), heart_function(t), fill='red', width=2)
    # 显示画布
    canvas.pack()
    root.mainloop()

if __name__ == '__main__':
    root = Tk()
    canvas = Canvas(root, bg='black', height=CANVAS_HEIGHT, width=CANVAS_WIDTH)
    draw_heart(root, canvas)
