Python

I highly recommend rtx over pyenv/asdf. For one thing, you'll still be able to which python and get a useful response, as it works by altering your PATH rather than relinking shims.

I use it everyday. I feel it’s my secret sauce in python dev… pyenv-virtualenv is pretty useful with it also

I found pyenv to be buggy at times, not properly setting the default (global) python version. I ultimately uninstalled pyenv and also uninstalled any additional Python installs outside of the system default.

Now, I do 100% of my Python work inside of Docker containers. This has solved any issues I’ve ever had with Python environments and PYTHONPATH . It’s also made me a stronger developer when it comes to using Docker.

I don’t see myself ever going back. A Docker container is the perfect Python environment.

When bringing people online from other languages, I first get them to find out what python there is in their environment and go with that if it's recent enough. Then I tell them about pyenv and it's plugins after a bit. Whenever I go straight into installing pyenv, it feels like I'm throwing some one in the deep ocean.

I've used pyenv for years and it's an awesome tool. Keeps python binaries separate and it has a virtualenv plugin. I've gotten others to use it as well.

It works great for library owners who need to run tox/nox on multiple versions of python in test suites. Love it.

Another useful Python version manager is asdf with python plugin. The most helpful feature of asdf is ability to specify what Python version to use in certain directory by simply placing a .tool-versions file (contains the version number to use) in that directory. This makes working with multiple projects that requires different version of Python very seamless.
