Why does it make you wince?

From a non-python dev perspective: I always struggle with dependencies and versions. I have a script in front of me that I want to run, and am often just frustratingly brute-forcing commands to make it work. Do I: python? python3? pip install? pip3 install? python pip install? python pip3 install? python3 pip install? python3 pip3 install? And then everyone mentions "oh just use venv" or "conda" or docker or... It ju…

Yeah, it's definitely painful. Over the years, I've probably spent in excess of 100 hours on understanding pip, venv, PYTHONPATH, poetry/pdm, pipfile, pyenv, ... still barely understand how it all works together.

https://peps.python.org/pep-0723/ might make life much simpler for single-script applications.

That's cool, but now for REAL bare-metal performance someone should rewrite Python in an even lower-level language. That's right, Python written in C is gonna be hella fast! Oh, wait…

I'm curious how large the WASM target is. One of the things that turned me off of C#'s Blazor WASM was the payload size. I've found some of Rust's offerings like yew and leptos more interesting.

It's okay-ish in size, ~10 MB, I made a small playground with an older version a while back: https://playground.cobalt.rocks/interactive

for simple scripts, this is the easiest and works.

  python3 -m venv venv
  source venv/bin/activate
  pip install whatever
  echo "source path/to/venv/bin/activate && python3 path/to/app.py" > myscript
  mv myscript /usr/local/bin
and just use myscript. I use this for a lot of little scripts

I think it's very naive for a programming language to make you "wince", tools are tools.

Python is a great language to Just Get Things Done™. Rust is great if you like puzzles and want to spend your precious time solving the same memory management riddle over and over again. You do get faster and often more robust code though, although in practice the difference is often not meaningful and the extra time invested doesn't pay off.

Sometimes, Things just can't be Done with Python. E.g., you're parsing dozens terabytes of data, or need response time within a microsecond.

So, you're left with a choice of C++, Rust (what else, C#, possibly Zig and a few other).

Rust stops being a "puzzle" once you've written enough of it and you just know how to do things. It has one major disadvantage though - returning back to write in languages like C++/Python makes you cringe because they don't have basic language tools like proper sum types or traits that get things done.
