from random import randint
from processing import *

numberOfParticules = 40;

def setup():
    size(300,300)

    for i in range(0, numberOfParticules):
        position.append([0,0])
        if (i < numberOfParticules/2):
            velocity.append([randint(-2,2), randint(-10,-5)])
            lifespan.append(randint(20,40))
        else: 
            velocity.append([0,0])
            lifespan.append(randint(0,40))

      point(position[i][0] + 150, position[i][1] + 300 )

      position[i][0]+=velocity[i][0]
      position[i][1]+=velocity[i][1]
      #Add Gravity
      velocity[i][1]+=0.2
      point(position[i][0] + 150, position[i][1] + 300 )
      
      #When a particules dies, another one appears
      lifespan[i]-=1
      if (lifespan[i] < 0): 
        velocity[i] = [randint(-2,2), randint(-10,-5)]
        position[i] = [0,0]
        lifespan[i] = randint(0,40)
        
        
def keyPressed():
    #print('A key was pressed', keyboard.key)
    #exitp()
    exit()

#The run() procedure below will call the setup() procedure followed by the draw() procedure.
#The draw() procedure will then be called 24 times per second (based on the frame rate set in the setup() procedure)

通过运行以上代码，您将看到一个简单的烟花特效在窗口中展示。每次运行程序，可能会看到不同的烟花效果，这取决于粒子的随机属性。

希望以上代码示例能帮助您理解如何使用Python制作烟花特效。您可以根据自己的需求和创意进一步扩展和优化代码，实现更加炫酷的效果。祝您编程愉快！
