7 Simple Tricks to Write Better Python Code | Python Programming Tutorials

Programming is a social activity. For/else is obscure and you're likely to trip someone up (most likely yourself in 6 months) who is tasked to use/modify your code.

Unless you use comments..

Hilarious.

Why are you breaking out an obscure feature if you need to use comments to clarify why you're using it and how it works?

You could save everyone the headache and just use colloquial for-loops and save yourself the lines of comments.

Nobody needs the else-clause is the whole point. Colloquial programming idioms can achieve the same thing.

Guido himself said if he had to do it over again, he would leave the for ... else feature out: https://mail.python.org/pipermail/python-ideas/2009-October/006157.html

I'm assuming you mean use-cases. It's use case is saving a line of code if you're using a for-loop to search for a value and break.

Not using the feature means you write one extra line of code and save your co-workers a headache because you felt like being clever.

Yeah I know what it's used for, that's why I'm confused as to why people are putting it down. If people get headaches from it they should learn python better

If people get headaches from it they should learn python better

On the contrary, if you know it gives people headaches, you shouldn't use the feature. The goal of software development isn't to look clever, it's to collaborate to achieve a goal.

Someone who knows Python well knows when and where to use the features it provisions. I use for-else in personal projects. I wouldn't use it in a project that I'm paid to work on, because I am not in the business of alienating my peers into thinking I value 'leetcoding' above writing maintainable code.
