I've been working on a few Python projects recently, and I've been thinking about how I can make the setup process easier. I've been using a few tools and libraries that have made my life easier, and I thought I'd share them with you.
- use
asdf
to install poetry and python - run a specific version of poetry to create the project directory
- inside the project directory pin poetry and python with
asdf local
- use
poetry
to add dependencies (likedjango
) - poetry also has a
run
command that can be used to run the django server (or any other commands you might want)
Add the asdf plugins.
> asdf plugin add python
> asdf plugin add poetry
Install python.
> asdf install python 3.10.10
Install poetry (the poetry plugin doesn't know how to translate latest
into a version number, so we have to look it up).
> asdf list all poetry | tail -n 1
1.8.1
> asdf install poetry 1.8.1
Ok. lets see what we got here.
> asdf list python
*3.10.10
3.11.7
3.7.4
3.9.18
> asdf list poetry
1.7.1
What about when we use the tools directly?
> poetry --version
Poetry (version 1.8.1)
> python --version
Python 3.10.10
👍 sterling.
Lets setup a new project.
> env ASDF_POETRY_VERSION=1.8.1 poetry new my-project
Created package my_project in my-project
> cd ./my-project
> asdf looal python 3.10.10
> asdf local poetry 1.8.1
Lets add Django.
> poetry add django
Creating virtualenv my-project-6y3EQ0-w-py3.10 in /home/zenobius/.cache/pypoetry/virtualenvs

Poetry is a tool for dependency management and packaging in Python. It allows you to declare the libraries your project depends on, and it will manage the installation and updating of these libraries for you. In a lot of ways these feels just like NPM/Yarn/Pnpm... for Python.
ASDF is a tool for managing multiple runtime versions. It's like NVM, but for more than just Node. It supports Python, Node, Ruby, Java, and pretty much anything you can write a simple bash plugin for.
