=== best practices
  * entornos virtuales: [[development:python:entornos-virtuales]]
  * paquetes: [[development:python:pip]]
  * instalar varias versiones python: [[https://medium.com/@julgq/instalando-m%C3%BAltiples-versiones-de-python-en-linux-ubuntu-20-04-2-lts-9f163c046cc5]]
  * How to use Python’s **py** launcher for Windows: [[https://www.infoworld.com/article/3617292/how-to-use-pythons-py-launcher-for-windows.html]]

  * Use ''Poetry'' for package management: <code bash>curl -sSL https://install.python-poetry.org | python3 -</code>

=== bootstrap
<code bash>
mkdir my-project && cd my-project
# Make sure the standard .gitignore is set
curl -o .gitignore https://raw.githubusercontent.com/github/gitignore/main/Python.gitignore
# init and activate virtual environment
python3 -m venv ./venv && source venv/bin/activate
# init Poetry. It will rely only the previously created venv, if activated.
poetry init -q
</code>

=== test
<code bash>
poetry add -g test flake8 autopep8 flake8-annotation
poetry install --only test
# Using Flake8 for lint
poetry run flake8 src
# Enforce styling
poetry run autopep8 --in-place --recursive src
# Using pytype for type checking
poetry run #TODO

</code>
