@Gracjandogg You would want measurements taken from production app, leverage monitoring to spot major bottlenecks, and make room for adjustments if the product owner says so, or the performance impact is so much your app is bleeding money.

That's the difference between a senior and a junior. Everything is a tradeoff, and you're better off investing the next hour building stuff that give you ROI, and not just anything you can detect that can be done better.

If you're talking about hot paths? Yes, BUT you will also have to inline any loops, and other things that simply shouldn't exist in non-hotpath code. In sort: You're not wrong, you're just taking things to the absolute extremes by choosing to not use stuff the standard library provides because "slow".

So smart!!! I love it ❤️❤️❤️

OVERENGINEERING a bit

You can search for 'Inline IF statement' or list comprehension. Basically when creating a variable you can put in that same line an IF logic to see what you will assign. For example "Size = 'small' if x < 10 else 'large'" Here depending on x the variable will be 'small' or 'large' in one line instead of having 4 lines.

My brain isn't working... what even?

Python is love

I had no idea you could use a list in the return like that. I love it.

Thank you so much for that.. my brain was starting to ache!!

Never let them know your next move xD

i got stuck cuz it kept on saying there was a problem with "filter_string" when the actual name was "filter_list"

Too Slow!

damn this is one of the best solutions of all time

It's slower tha others
