### 回答1:
print("烟花开始")
for i in range(10):
print(" "*i + "*")
for i in range(11):
print(" "*(10-i) + "*"*(2*i-1))
for i in range(10):
print(" "*(9-i) + "*"*(2*i+1))
print("烟花结束")

烟花是一种美丽的燃放装置,在夜晚点燃后喷发出绚丽的火花和闪耀的光线。下面是一个简单的Python代码示例,可以实现烟花效果:
```python
import turtle
import random
# 设置绘画窗口的属性
win = turtle.Screen()
win.title("Fireworks")
win.bgcolor("black")
# 创建一个烟花粒子类
class FireworkParticle(turtle.Turtle):
def __init__(self, color):
turtle.Turtle.__init__(self)
self.shape("circle")
self.color(color)
self.penup()
self.speed(0)
self.shapesize(stretch_wid=0.2, stretch_len=0.2)
def move(self):
self.fd(2)
self.rt(random.randint(0, 359))
# 创建一个烟花类
class Firework:
def __init__(self):
self.particles = []
def explode(self):
for _ in range(50):
particle = FireworkParticle(random.choice(["red", "orange", "yellow", "green", "blue", "purple"]))
particle.goto(0, 0)
particle.setheading(random.randint(0, 359))
self.particles.append(particle)
def fade(self):
for particle in self.particles:
size = particle.shapesize()[0]
particle.shapesize(size-0.1)
particle.color((0, 0, 0, 255))
# 创建一个烟花管理类
class FireworkManager:
def __init__(self):
self.fireworks = []
def create_firework(self):
firework = Firework()
firework.explode()
self.fireworks.append(firework)
def fade_fireworks(self):
for firework in self.fireworks:
firework.fade()
if firework.particles[0].shapesize()[0] <= 0:
self.fireworks.remove(firework)
# 创建一个烟花管理器对象
manager = FireworkManager()
# 设置画笔的属性
pen = turtle.Turtle()
pen.hideturtle()
pen.speed(0)
# 循环绘画
while True:
manager.create_firework()
manager.fade_fireworks()
for firework in manager.fireworks:
for particle in firework.particles:
particle.move()
if len(manager.fireworks) == 0:
pen.clear()
pen.color("white")
pen.write("点击窗口退出", align="center", font=("Courier", 24, "normal"))
break
# 点击窗口退出
win.exitonclick()
```
这个代码使用了Python的turtle库来绘制烟花效果。运行代码后,会在绘图窗口中不断绽放烟花,并逐渐消失。按需求或者个人喜好,可以对代码进行进一步修改来实现更加丰富的烟花效果。

下面是一个简单的Python代码示例,用于实现一个基本的烟花效果:
```python
import turtle
import random
screen = turtle.Screen()
screen.bgcolor("black")
colors = ["red", "blue", "green", "purple", "yellow", "orange"]
def create_firework(x, y):
firework = turtle.Turtle()
firework.shape("circle")
firework.color(random.choice(colors))
firework.shapesize(0.2)
firework.penup()
firework.goto(x, y)
return firework
def explode_firework(firework):
for _ in range(20):
firework.right(random.randint(0, 360))
firework.forward(100)
firework.stamp()
firework.goto(0, 0)
def launch_firework(x, y):
firework = create_firework(x, y)
firework.speed(0)
firework.pendown()
firework.goto(x, y+150)
firework.penup()
firework.hideturtle()
explode_firework(firework)
screen.onclick(launch_firework)
turtle.done()
```
这段代码使用了Python的turtle模块来绘制烟花效果。点击屏幕的任意位置,会在该位置生成一个烟花,然后烟花会向上飞行,并在到达顶点时突然爆炸,形成多个小火花飞溅的效果。每个小火花由彩色的圆点表示。
在代码中,我们创建了两个函数:`create_firework`用于创建一个烟花,`explode_firework`用于让烟花爆炸。`launch_firework`函数通过调用前两个函数来完成烟花的生成和爆炸过程。
这只是一个简单的烟花效果示例,如果你希望烟花效果更加丰富,你可以尝试修改代码,例如可以添加更多颜色、调整烟花的形状、增加爆炸的粒子数量等等。
