要使用 Python 制作烟花特效，可以使用 Pygame 库来进行图形绘制和动画效果的实现。以下是一个简单的例子代码，用于绘制烟花特效：

import pygame
import random

# 初始化 pygame
pygame.init()

# 设置窗口大小 
width, height = 800, 600
screen = pygame.display.set_mode((width, height))

# 定义颜色 
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)

# 烟花粒子类 
class Particle:
    def __init__(self, x, y, size):
        self.x = x
        self.y = y
        self.size = size
        self.color = (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))
        self.speed = random.randint(1, 5)

    def move(self):
        self.y -= self.speed

    def draw(self):
        pygame.draw.circle(screen, self.color, (self.x, self.y), self.size)

# 创建烟花粒子 
def create_particles(x, y):
    particle_count = 20
    for _ in range(particle_count):
        particle = Particle(x, y, random.randint(2, 5))
        particles.append(particle)

# 主循环 
running = True
particles = []
clock = pygame.time.Clock()

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

        if event.type == pygame.MOUSEBUTTONDOWN:
            mx, my = pygame.mouse.get_pos()
            create_particles(mx, my)

    # 清空屏幕 
    screen.fill(BLACK)

    # 更新和绘制烟花粒子 
    for particle in particles:
        particle.move()
        particle.draw()
        if particle.y <= 0:
            particles.remove(particle)

    # 刷新屏幕 
    pygame.display.flip()
    clock.tick(60)

# 退出程序 
pygame.quit()
