You Can Do WHAT With While Loops?!?

You can do what with while loops?!? #python #code #shorts

"Python isn't cursed."
*The while else:*

"Extra Hidden Functionality" is Python's middle name.

For anybody wondering, this also works with for loops

[LauPaSat-pl]

If anyone wonders why it's called "else", that's because any loop is under the hood if+go to statements. I recommend watching mCoding video on the subject

I know of this for 20 years, and coded in Python for 20 years, and there was not a single time i used this feature. Simply in practice it never is what you actually want to do, plus it introduces extra indentation level.

[rockstardonut]

Use this if you want other people to be confused with the code flow.
Just because the syntax exists doesn't mean you should use it as it is likely to cause bugs because people are not aware of this.

[karanveersingh]

You can just print success or any other stuff after the while loop has ended without writing else clause. It looks cool but it’s useless. No?

[codeiscool]

i didn't know this and this solves most of my loop based problems

[tocraft]

It doesn’t make grammatical sense at all, this feels like a bug that was implemented as a “feature”

I've been using Python since 1996 and while (groan) I have always known this has existed, I have still yet to find a use case for it.

[Landonismo]

I've been coding in python for almost 10 years and I learn something new from this channel every day. Kudos!

[JordanMetroidManiac]

I have always thought of it as “if it doesn’t break, then something went wrong, so go into the else…”

[DoolanDrum]

"extra hidden functionality" that's right there in the docs

[zee-anime]

This will be perfect for writing esoteric code

[humanrightsadvocate]

So if it fails, it's a success. Got it!

I don't understand why everyone is hating on else being used in a while loop, it seems pretty useful. Like in this example the condition is no longer met, and it tells you that. I can imagine instances where knowing the condition is no longer satisfied could be useful.

[Andris_Briedis]

This is a prime example of what I don't like about formatted languages - like python. If you look at the code, what do you see. While and else together on the same level. WTF is the first thing that comes to mind. Instead of devoting all your attention to the nature and purpose of the code, you have to take the time to understand its syntax.

[major]

Its works for "FOR" loop too 💀

[simonmasters]

I would expressly test if i>2
Also continue would take away some of the goto worries...
Presumably whiles using list comprehension can also have these else: statements

[shiinondogewalker]

I think while then would sound more natural
