I've never used it because the (unknown) effort of switching and the chance of compatibility issues have always made it unappealing compared to just switching to a faster language.
If I could just `pip3 install pypy` and then set an environment variable to use it or something like that then I'd give it a try. It does feel a bit like adding a jet pack to a rowing boat though. I know some people use Python in situations where the performance requirement isn't "I literally don't care" but surely not very many?
Obviously if it was the default that would be fantastic.
If you use a version manager like rtx or asdf then it’s basically that simple. I just had to run a single command:
This downloaded and installed PyPy v3.10 in a few seconds and created an .rtx.toml file in the current directory that ensures when I run python in that directory I get that version of PyPy.
