So I've got something of the form:

def func():
  while True:
    do_stuff()

try:
  func()
except:
  func()

I had expected that if anything happened to my func loop, it would start again, however in actual fact errors cause it to crash. How can I make it just restart if anything goes wrong?

    I think you should rely on shell script for this matter. – Nihal Feb 06 '19 at 08:11

    So you program will still work on out of memory exceptions? – RedX Feb 06 '19 at 08:14
  • @RedX can we do it like: use all the exception except `out of memory` exception? in python? – Nihal Feb 06 '19 at 08:16

    @Nihal Of course you can always make a whitelist or blacklist but my point is that the simple requirement shows no real thought and should be reconsidered. – RedX Feb 06 '19 at 08:19

You can try placing the try-except inside a while loop and use pass in the except block.

Ex:

def func():
  while True:
    do_stuff()

while True:
    try:
        func()
    except:
        pass

What are you trying to achieve? Keeping a program run is generally not the responsibility of the program itself. If you are on a UNIX-like operating system, you can use Supervisord to automatically run processes and let them restart if they fail. If you are on Windows, this answer may help you out!

Try to put loop contents inside try except statements

def func():
    while True:
        try:
            do_stuff()
        except:
            continue
func()
