 # py-template
-Template for a new python project
+This repository serves as a template for new python projects and a way to express best practices
+
+## Best Practices - Coding Practices
+
+### User input
+* Always use [`argparse`](https://docs.python.org/3/library/argparse.html) for command-line arguments
+* Assume the use of [`yaml`](https://python.land/data-processing/python-yaml) for structured input files unless there are compelling reasons for something else
+
+### User output
+* Always use `logger` for status output
+* Carefully choose an output format for standard formats, considering the following in order of priority:
+    * [CSV](https://docs.python.org/3/library/csv.html) with direct support in NumPy, Pandas, etc
+    * [yaml](https://python.land/data-processing/python-yaml)
+    * [json](https://docs.python.org/3/library/json.html)
+    * [HDF5](https://www.h5py.org/)
+    * SQL, for example [SQLite](https://docs.python.org/3/library/sqlite3.html)
+
+### Modularity
+* All runnable scripts [should include a block like](https://stackoverflow.com/questions/419163/what-does-if-name-main-do):
+
+``` python
+if __name__ == "__main__":
+    do_main_task()
+```
+
+### Testing
+* Always use [`pytest`](https://docs.pytest.org/en/8.2.x/) for testing
+* Introduce a simple continuous integration (CI) action ASAP
+
+### Collaboration
+* Generate pull requests (PRs) with as little code change as possible
+* Include tests in all PRs
+* Do not merge your own PR; there should always be at least one review by a
+  non-author, and a non-author should merge
+
+### Packaging and installation
+* Introduce a `pyproject.toml` file ASAP
+
+## Best Practices - Style
+
+### Code formatting
+* Follow PEP8 style guide, ideally with a tools like
+  [`black`](https://pypi.org/project/black/) to help enforce it, especially via
+  a plugin to your editor
+
+### Variable naming
+* Generally, choose nouns for variables and verbs for methods
+* Clear variable and method names can reduce the need for comments
+
+### Comments
+* Include a docstring in every method
+* Rely on clear variable and method names and add comments sparingly where the
+  intent/approach is non-intuitive
+
+### Modularity
+* If you have cut & paste code in two different places, it probably should be a
+  method
+* Even very short methods can be valuable if the method name makes the code more
+  readable
+* Ideally, methods should be no longer than one screen worth of lines
