Python development thread to implement the Brown Movement method, pythonthread

This article describes how to implement the Brown motion using the thread in python development. We will share this with you for your reference. The details are as follows:

Here I will introduce you to an example of implementing the Brown motion using the thread in python.

The following figure shows the running effect:

Code Section:

# Brownian motion -- an example of a multi-threaded Tkinter program. from tkinter import * import randomimport threadingimport timeimport sys # canvas size WIDTH = 400 HEIGHT = 300 SIGMA = 10 BUZZ = 2 RADIUS = 2 LAMBDA = 10 FILL = 'red' stop = 0 # Set when main loop 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) dy = random. gauss (0, BUZZ) dt = random. expovariate (LAMBDA) try: canvas. move (p, dx, dy) failed t TclError: break time. sleep (dt) def main (): global stop root = Tk () canvas = Canvas (root, width = WIDTH, height = HEIGHT) canvas. pack (fill = 'both ', expand = 1) # number of particles np = 30 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 = 1 main ()

I hope this article will help you with Python programming.
