Created page with "== Overview == This is where I collect best practices related to Python. == Setup == === Python 2 or Python 3? === Python 3.<ref>Unless it is an existing project or absolute..."

New page

== Overview ==
This is where I collect best practices related to Python.

== Setup ==
=== Python 2 or Python 3? ===
Python 3.<ref>Unless it is an existing project or absolutely depends on a package that is only compatible with Python 2. All new projects should target latest version of Python 3.</ref>

=== Pyenv ===
To manage different versions of Python on your machine, use [https://github.com/pyenv/pyenv pyenv]. To install see:

* https://github.com/pyenv/pyenv#installation

Once it's installed, install the version of Python you want:

<pre>$ pyenv -v
pyenv 1.2.6

$ pyenv install -l
Available versions:
2.1.3
2.2.3
...
3.8-dev
3.8.1
3.9-dev
...
stackless-3.4.7
stackless-3.5.4

# Install latest stable version of Python 3. At this time: 3.8.1
$ pyenv install 3.8.1
$ pyenv global 3.8.1
$ pyenv global
3.8.1
$ python -V
3.8.1
</pre>

=== Pip ===
To manage dependencies, use [https://pip.pypa.io/en/stable/ pip]. (It is installed with pyenv.)

== Project Structure ==
For guidance on project structure, see the following:

* https://stackoverflow.com/questions/193161/what-is-the-best-project-structure-for-a-python-application
** Especially this answer: https://stackoverflow.com/a/3419951/9381758
* http://docs.python-guide.org/en/latest/writing/structure/
* https://github.com/kennethreitz/setup.py

== Style Guide ==
Unless otherwise noted, follow [https://www.python.org/dev/peps/pep-0008/ PEP 8].

* Use spaces not tabs.
* Indent 4 spaces.

=== Code Analysis ===
Use of a code analyzer, or linter, is strongly encouraged. We use flake8:

* http://flake8.pycqa.org/en/latest/
