How to implement Brownian motion with the thread of Python development

In this paper, we describe the method of developing the thread of Python to implement Brownian motion. Share to everyone for your reference, as follows:

Here I will give you an example of the thread in Python to implement Brownian motion.

Here's how it works:

Code section:

# Brownian Motion--an example of a multi-threaded Tkinter program.from Tkinter import *import randomimport threadingimpo RT timeimport sys# Canvas Size width = 400HEIGHT = 300SIGMA = 10BUZZ = 2RADIUS = 2LAMBDA = 10FILL = ' Red ' stop = 0 # Set when main l OOP exitsdef particle (Canvas):  r = RADIUS  x = Random.gauss (width/2.0, SIGMA)  y = Random.gauss (height/2.0, SIGMA)  p = canvas.create_oval (X-r, Y-r, X+r, Y+r, Fill=fill) while not  stop:    dx = Random.gauss (0, BUZZ)    D y = Random.gauss (0, BUZZ)    dt = random.expovariate (LAMBDA)    try:      canvas.move (P, dx, dy)    except Tclerror :      break    time.sleep (DT) def main ():  global stop  root = Tk ()  canvas = canvas (root, Width=width, Height=height)  canvas.pack (fill= ' both ', expand=1)  #粒子数目  np =  if sys.argv[1:]:    np = Int ( SYS.ARGV[1]) for  I in range (NP):    t = Threading. Thread (target=particle, args= (canvas))    T.start ()  try:    root.mainloop ()  finally:    stop = 1main ()

I hope this article is helpful for Python program design.
