用编程绘制从下向上的烟花

下面是python语言绘制从下向上的烟花的代码：

import turtle

from random import randint

# 设置画布大小

turtle.setup(800, 600)

# 设置画笔

turtle.pensize(3)

# 设置画面颜色和速度

turtle.bgcolor('black')

turtle.speed(10)

# 设置颜色列表

colors = ['red', 'yellow', 'blue', 'green', 'purple', 'orange']

# 定义绘制烟花的函数

def draw_firework():

# 设置画笔随机颜色

color = colors[randint(0, len(colors)-1)]

turtle.color(color)

# 绘制烟花的中心点

turtle.penup()

turtle.goto(0, -300)

turtle.pendown()

turtle.dot(20)

# 绘制烟花的线条

turtle.penup()

turtle.goto(-200, -300)

turtle.pendown()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.goto(randint(-200, 200), randint(100, 500))

# 绘制烟花的花朵

turtle.penup()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.pendown()

turtle.dot(10)

turtle.penup()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.pendown()

turtle.dot(10)

turtle.penup()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.pendown()

turtle.dot(10)

turtle.penup()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.pendown()

turtle.dot(10)

turtle.penup()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.pendown()

turtle.dot(10)

# 清除烟花的轨迹

turtle.penup()

turtle.goto(-200, -300)

turtle.pendown()

turtle.color('black')

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.goto(randint(-200, 200), randint(100, 500))

# 绘制烟花的爆炸效果

turtle.penup()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.pendown()

turtle.dot(100, color)

turtle.penup()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.pendown()

turtle.dot(100, color)

turtle.penup()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.pendown()

turtle.dot(100, color)

turtle.penup()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.pendown()

turtle.dot(100, color)

turtle.penup()

turtle.goto(randint(-200, 200), randint(100, 500))

turtle.pendown()

turtle.dot(100, color)

# 绘制多个烟花效果

for i in range(10):

draw_firework()

# 隐藏画笔

turtle.hideturtle()

# 停在画面上

turtle.done()

运行上面的代码，可以绘制出从下向上的烟花。每次运行程序，都会有不同的烟花效果。
