Question

I’m new to Python and I’m writing a script that
includes some timed routines.
My current approach is to instantiate a class
that includes those Timers (from: threading.Timer),
but I don’t want the script to return when it gets to the
end of the function:

import mytimer

timer = mytimer()

Suppose I have a imple script like that one. All it
does is instantiate a mytimer object which performs a series
of timed activities.

In order for the application not to exit, I could use Qt like this:

from PyQt4.QtCore import QCoreApplication
import mytimer
import sys

def main():
    app = QCoreApplication(sys.argv)
    timer = mytimer()

    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

This way, the sys.exit() call won’t return immediately, and the
timer would just keep doing its thing ‘forever’ in background.

Although this is a solution I’ve used before, using Qt just for this doesn’t
fell right to me.
So my question is, Is there any way to accomplish this using standard Python?

Thanks

Answer 1

Create a function in your script which tests a select or poll object to terminate a loop. Check out serve_forever in SocketServer.py from the standard library as an example.
