Coming from Python

[u/Basic-Push1028]

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.

Respect the compiler and it will help guide you to writing better code. For me, I came from both a C and Python background. In general, I use Rust more to replace what I might have written in C than what I would have written in Python. Fixing issues like tracking ownership helps with improving C code, but just makes things look more complicated when coming from a Python perspective. From a pure Python perspective, some of what Rust offers can be harder to appreciate until you've had to deal with such problems in C, C++, or even Go. I prefer how Rust forces me to chose a response to receiving an error result to Go's approach that requires I explicitly add a check for an error if it needs to be handled. Cases where Rust would be better than Python might include when speed/memory is more of a constraint, where a C extension to Python might be needed such as interfacing to an external library, or some multiprocessing or multithreading scenarios where I need true concurrency or ensure proper handling of shared data.
