使用Python和Tkinter库

这是一个使用Python的Tkinter库绘制滚动爱心画面的示例代码:

```python

import random

from math import sin, cos, pi, log

from tkinter import *

调整画布

CANVAS_WIDTH = 640

CANVAS_HEIGHT = 480

CANVAS_CENTER_X = CANVAS_WIDTH / 2

CANVAS_CENTER_Y = CANVAS_HEIGHT / 2

IMAGE_ENLARGE = 11

HEART_COLOR = "FFC0CB"

爱心生成

def heart_function(t, shrink_rat):

x = 16 * (sin(t) 3)

y = 13 * cos(t) - 5 * cos(2 * t) - 2 * cos(3 * t) - cos(4 * t)

return (CANVAS_CENTER_X + x * shrink_rat, CANVAS_CENTER_Y + y * shrink_rat)

创建主窗口

root = Tk()

canvas = Canvas(root, width=CANVAS_WIDTH, height=CANVAS_HEIGHT)

canvas.pack()

绘制爱心动画

frame_rate = 30

last_time = time.time()

shrink_rate = 1.0

while True:

current_time = time.time()

elapsed_time = current_time - last_time

last_time = current_time

if elapsed_time > 1 / frame_rate:

t = elapsed_time * frame_rate

x, y = heart_function(t, shrink_rate)

canvas.create_oval(x - 5, y - 5, x + 5, y + 5, fill=HEART_COLOR)

shrink_rate -= 0.005

if shrink_rate < 0:

shrink_rate = 1.0

root.update_idletasks()

root.update()

```

使用Python和matplotlib库

这是一个使用Python的matplotlib库绘制滚动爱心画面的示例代码:

```python

import numpy as np

import matplotlib.pyplot as plt

import matplotlib.animation as animation

设置爱心的参数

a = 1

t = np.linspace(0, 2 * np.pi, 100)

x = a * (16 * np.sin(t) 3)

y = a * (13 * np.cos(t) - 5 * np.cos(2 * t) - 2 * np.cos(3 * t) - np.cos(4 * t))

创建绘图窗口

fig, ax = plt.subplots()

ax.set_xlim(-1.5 * a, 1.5 * a)

ax.set_ylim(-1.5 * a, 1.5 * a)

ax.set_aspect('equal')

ax.axis('off')

初始化爱心

line, = ax.plot(x, y, color='red', linewidth=2)

更新动画的函数

def update(frame):

x_offset = 0.5 * np.sin(frame / 10)

line.set_data(x + x_offset, y)

return line,

创建动画

ani = animation.FuncAnimation(fig, update, frames=np.arange(0, 2 * np.pi, 0.1), blit=True)

plt.show()

```

使用Python和turtle库
