The simplest way to keep a program running “forever” is to put your code in a while loop and set the condition to True.
For certain situations, an infinite loop may be necessary. A very basic way of creating an infinite loop in Python is to use a while statement. This is shown below. This goes on forever and ever, unless the program is terminated.
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.
