Question

I made an IRC bot which uses a while true loop to receive whatever is said.
To receive I use recv(500), but that stops the loop if there isn’t anything to receive, but i need the loop to continue even if there isn’t anything to receive.
I need a makeshift timer to continue running.

Example code:

/A lot of stuff/
timer=0
while 1:
    timer=timer+1
    line=s.recv(500) #If there is nothing to receive, the loop and thus the timer stop.
/A lot of stuff/

So either I need a way to stop it stopping the loop, or I need a better timer.

You can settimeout on the socket so that the call returns promptly (with a suitable exception, so you’ll need a try/except around it) if nothing’s there — a timeout of 0.1 seconds actually works better than non-blocking sockets in most conditions.
