Django 应用程序 - 服务器上的数据处理

Question

I have some question about some django app.

Simple example:

On the server I'd like to run some program, which should display some value. Example:

for(i in range(10)):
    print(10**i)
    sleep(1)

So value changes every 1 second without refreshing. It could be some progress bar etc.

How to start with it? Celery is the good start? What should I look for?

Best regards!

Edit: It could be somethink like progress bar etc.

For example only x% value on my page. And some data should be processed in the background.

You know what I mean?

You can use Twisted which is a Python networking library.

From the documentation:

from twisted.internet import task, reactor
timeout = 60.0 #specify interval over here in seconds

def doWork():
    #do whatever work you want to do here
    pass

rep_work = task.LoopingCall(doWork)
rep_work.start(timeout) # call every sixty seconds
reactor.run()
