python生日快乐代码+烟花

### 使用Python创建带有烟花效果的生日祝福

为了实现一个具有烟花效果的生日祝福程序，可以利用`tkinter`库处理图形用户界面，并结合`turtle`库制作动态特效。下面是一个综合运用这两个库的例子：

#### 导入必要的库

import tkinter as tk
from turtle import RawTurtle, TurtleScreen
import random
import time

#### 创建窗口并初始化画布

root = tk.Tk()
cv_width = 800
cv_height = 600
canvas = tk.Canvas(root, width=cv_width, height=cv_height, bg="black")
canvas.pack()

screen = TurtleScreen(canvas)
screen.bgcolor("black")

def draw_firework(x, y):
    """在指定位置绘制单个烟花"""
    firework = RawTurtle(screen)
    colors = ['red', 'blue', 'yellow', 'green']
    
    firework.penup()
    firework.goto(x, y)
    firework.pendown()
    
    color = random.choice(colors)
    size = random.randint(5, 20)

    firework.color(color)
    firework.dot(size * 2)  # 中心亮点
    
    for _ in range(random.randint(10, 20)):
        angle = random.uniform(-90, 90)
        distance = random.uniform(30, 70)
        
        firework.setheading(angle)
        firework.forward(distance)
        firework.backward(distance)
        firework.right(180 - (angle % 180))
        firework.dot(int(size / 2), color)
        firework.home() 

for i in range(10):  
    x = random.randint(-int(cv_width/2)+50, int(cv_width/2)-50)
    y = random.randint(-int(cv_height/2)+50, int(cv_height/2)-50)
    draw_firework(x, y)
    screen.update()
    time.sleep(.5)

message_turtle = RawTurtle(screen)
message_turtle.hideturtle()
message_turtle.speed('fastest')
message_turtle.penup()
message_turtle.goto(0,-50)
message_turtle.write("Happy Birthday!", align='center', font=('Arial', 40, 'bold'))
message_turtle.goto(0,-100)
message_turtle.write("Wish you all the best.", align='center', font=('Arial', 20, 'normal'))

root.mainloop()

这段代码首先设置了基本的Tkinter窗口和Canvas组件作为背景板，在其上使用Turtle对象模拟了多个随机分布的烟花爆炸场景[^1]。最后显示了一条生日贺词。
