Console? good, GUI? good, game dev? use Godot engine with its similar language Gdscript, but what else? Ive been seeing AI, Data Science stuff, but whats the point if ita slow?

Python is slow enough to notice in fairly normal usage. Just doing lookups into a dict with thousands of entries, for example, will lead you to researching how to sort and index it.
Python’s great as an interface to C which gives it the illusion of performing well.
Yeah, want to take a bet on how long a single lookup in a dict with 5,000 entries takes on my machine?
It’s a hash table. Can you explain why “sorting and indexing” would improve performance?
You’re talking out your arse.
And honestly - what do you expect for a response with a shitty attack like that? Do you need to be a dick?
I mis-remembered, it was a linear search though a list rather than a dict that was the problem (I think it was a list because we were looking up multiple entries or something from a list of Objects based on a field). O(N) lookup to be sure so not well optimized. But on list of 100,000 items doing 100,000 lookups it is very slow - > 1 minute whereas in Java it was like a few seconds.
Yes - refactoring was the solution. I’m not saying it couldn’t perform better and it did when we re-wrote it. But that’s a low-enough number of items that it surprised me that it was a problem.
An order of magnitude difference between python and java would not surprise me at all, sure.
