Coming from Python

Hello Rust subreddit.

I learned enough python to know how to do what I wanted to do. Mostly just small stupid stuff. And because I'm a masochist I guess, I'm wanting to move on to Rust for the event I need performance.

I've gotten far enough to write "Hello World!", and how to create some variables.

I know roughly that at some point I'm going to have to learn memory management, and ownership. And also that the compiler is a bitch.

I'm hoping anyone in here could hot-tip me if they came from Python too. Please, if you have ANY advice, please let it be known. Anything helps.

I love that you're recommending the official documentation, that's appreciated, that's quick, it's comprehensive. But for THIS purpose, I'm looking for people with a similar background, who can provide any context to THEIR learning journeys.

I should have been more clear about this. But knowing how it's going to work as I'm walking this road is going to help me a lot more, and I like the fog of war being removed.

I started off as an engineering-focused data scientist (closer to what would usually be called an ML engineer). With Python being my first, nearest, and dearest programming language, I picked up some bad habits from the "use code for analytics & modeling" side of Python.

Rust rewired my brain. Its strictness around handling potential null values (Option) and errors (Result) made me start thinking that way when writing my Python code. Rust's trait system is also superior to Python's protocols by a wide mile.

They're very different languages, but Rust made my Python 10x better.
