I Didn't Know That Python's For Loops Could Do THIS 🙈

I didn't know that Python's for loops could do this. #Python #Code #Shorts

That syntax is confusing. Why would the else block execute when all conditions pass? That should have been named finally.

[itznukeey]

this literally feels like a bug not a feature

[SuperElephant]

How confusing do you want your language to be developed? Yes.

I accidentally found this by wrongly typing

[patocarrasco]

a bit more precise is to say that the 'else' statement runs when the condition of the 'for' loop turns false.

In the case of 'range(3)', let's say that it is equivalent to giving a list '[0, 1, 2]', which has three elements. The condition for looping through an iterable (the list in this case) is that it must have remaining items. After you reach '2' (third item) and print it, python goes back, checks the list and it turns to be that you are out of items, then the condition to loop through the list becomes 'false' and the 'else' statement gets triggered.

From what I've heard from other devs this is considered to be bad practice. It makes it harder to read as its wording is unintuitive.

[adventuresofavalon]

This can be done in while loop as well

Man thanks i had a programming problem
Which prints * inside the loop and has a if statement with break when the number equals certain number . I couldn’t get why after executing the for loop the else part was not executing….
Your video helped me

This is bad practice. Even Python’s developers said they regretted including this because of its unintuitive behavior.

This isn't exactly a feature that is touted around much hence why very few people know about it.

Even the creator regrets making it because he admits that the syntax is confusing and it isn't really useful.

You can get a full explanation as to why you shouldn't use it if you look up mCoding. He does a pretty good job explaining why it's bad lol.

[benbabu]

This becomes useful in cases like finding whether a number is prime or not

[RocketLR]

Oh it needs to break..
This just solves a issue i suspect is in my script that i was working on last week. Hope i remember to fix it on monday 😅

[sunwukong]

if i = 1 <- this will never give back “True”

[zeldaplayergl]

Me: Knowing this
Also me: Never using it 🤣

[gazzalifahim]

The "else" name seems confusing here, btw 😅

[Alexthatsnottaken]

I think for might stand for "if or" cause you get if i = 0, or i =1 or etc

[cimmik]

I can't think of a situation where that would be useful

[humanrightsadvocate]

They say Python is user friendly and easy to learn. They lied. Syntax like this makes absolutely no sense. ELSE is supposed to be executed if the main thing is false. That's why it's called ELSE, it's the other branch!!!

[oscareriksson]

It seems useful as a feature. But the key word 'else' seems very random. Should have been another key word like 'all' or 'finished' or 'complete' or something

[junyulu]

it should be 'finished' or 'finally' or something like this but not using 'else' as the name
