2:30 it literally said, "You can run, but you can't escape" 💀

[@IdPreferNot1]

Love the quick explanations

[@dandyexplorer4252]

You can actually escape it. When I ran: from os import _exit try: print('a') _exit(0) finally: print('b') I got: a

[@it_is_random]

I know cuz I am a python dev with big brain try: sys.exit()

[@RocktCityTim]

In that case, you've stepped out of your normal flow since the _exit() is used to force exit the process with specified status without calling cleanup handlers, flushing buffers, or any other end of process steps.

It’s like pulling the power plug when your computer hangs and say you manually shut it down

[@RocktCityTim]

@@applecastaway4256 Exactly - if you're in the middle of a big edit on your system and pull the plug, anything not saved at the loss of power is lost - and, if the filesystem doesn't offer proper synchronization, the filesystem itself could become corrupted.

very helpful

[@rijuroy7415]

Loved it

[@vishnubalaji9500]

so will this function always execute if or breaks? def f(): try: except: finally: continue

[@daniloelias9887]

I knew of all of these features already, but i really hoped you would show a use case in which this super power, which I agree it is one, is actually useful or necessary... 'finally' is weird and fun to play with, but I coudnt find in 9 years of coding one situation in which it saved me or was actually necessary... BTW I love this channel thanks for everything you post, this is me ranting because of finally not you, thanks from brazil

[@thomasbrotherton4556]

Surprised you didn’t mention the else option of try

[@Programing2024]

What phone do you use?
