How to run a script forever? [duplicate]

I need to run my Python program forever in an infinite loop..

Currently I am running it like this -

#!/usr/bin/python

import time

# some python code that I want 
# to keep on running


# Is this the right way to run the python program forever?
# And do I even need this time.sleep call?
while True:
    time.sleep(5)

Is there any better way of doing it? Or do I even need time.sleep call? Any thoughts?

Yes, you can use a while True: loop that never breaks to run Python code continually.

However, you will need to put the code you want to run continually inside the loop:

#!/usr/bin/python

while True:
    # some python code that I want 
    # to keep on running

Also, time.sleep is used to suspend the operation of a script for a period of time. So, since you want yours to run continually, I don't see why you would use it.

How about this one?

import signal
signal.pause()

This will let your program sleep until it receives a signal from some other process (or itself, in another thread), letting it know it is time to do something.

I know this is too old thread but why no one mentioned this

#!/usr/bin/python3
import asyncio 

loop = asyncio.get_event_loop()
try:
    loop.run_forever()
finally:
    loop.close()

sleep is a good way to avoid overload on the cpu

not sure if it's really clever, but I usually use

while(not sleep(5)):
    #code to execute

sleep method always returns None.
