My secret to high uptime:

while True:
    try:
        main()
    except:
        pass

Lurking beginner here, why is this bad?

Basically sweeps errors under rug.

No error handling and go again.

There you go:

# Start an infinite loop because True will always be True
while True: 
    # try to run the main function, usually where everything happens
    try:
        main()
    # in the case an exception is raised in the main function simply discard (pass) and restart the loop
    except:
        pass

Thank you for that answer! That makes sense.

This gives some better context. https://stackoverflow.com/questions/21553327/why-is-except-pass-a-bad-programming-practice

But essentially ignoring every single error a program could generate is not great. It'd be better to know what those errors are and fix/prevent them from occurring in the first place.
