Python 3 Boilerplate for Non-Productive environments (e.g., Kata, Study)

Jul 28, 2024 - 1 minute read - Comments - 2024 boilerplate github july kata makefile python repository study

I have created a Python 3 boilerplate for non-productive environments. It can be found here: https://github.com/alvarogarcia7/python-boilerplate

Main features

Its main features are:

It can be run locally (local python) or in a docker container (official docker image)
It has a Makefile with the most common commands to drive the project. Also, other makefiles in this folder
Batteries included: mypy, pytest, pre-commit.
Permissive license: MIT. The updated version is here
Currently, it is using python 3.12

Usage

Clone the repository under a new project name. Either with Downloading the ZIP file or with git clone.
If present, remove the .git folder and create a new one.
Start adding features
Push to a new repository of your own.

Limitations

Limitations:

It is not a template, but a starting point. You will need to change the name of the project, the name of the package, and the name of the module
It is not a production-ready project. It is intended for katas, study, or similar non-productive environments.

Other

Note: The views expressed in this repository are my own and do not necessarily reflect the views of my employers (past, present, or future).

Re: Do people IRL know you have a blog?

No one else has anything invested in this. No one cares if you do it, or don’t do it. To the world this pursuit is just your cute little hobby.

There’s a constant tug of war between wanting to be professional and wanting to be cool online. Sometimes those things overlap and sometimes they don’t. And sometimes the folks who have the opportunities to make a weirdo website are doing so because they’re not financially dependent on their website selling a service or landing a new gig. Their economic livelihood isn’t at risk if someone is turned off by the strange fonts or experimental navigation on their website.

A discussion he had with his wife about having a blog prompts the question of what is the purpose of the personal blogs.

The author does not mind if they are useful to other people or not; it’s not a source of income.

Another comment: My blog is primarily a way for me to clarify my thoughts on a topic by writing about it. Once that is done, the amount of effort required to post those thoughts is small, so why not do it?.

A bunch of programming advice I’d give to myself 15 years ago

learnings from a senior developer to a more younger self:

If you (or your team) are shooting yourselves in the foot constantly, fix the gun
Assess the trade-off you’re making between quality and pace, make sure it’s appropriate for your context
Spending time sharpening the axe is almost always worth it
If you can’t easily explain why something is difficult, then it’s incidental complexity, which is probably worth addressing
Try to solve bugs one layer deeper
Don’t underestimate the value of digging into history to investigate some bugs
Bad code gives you feedback, perfect code doesn’t. Err on the side of writing bad code
Make debugging easier
When working on a team, you should usually ask the question
Shipping cadence matters a lot. Think hard about what will get you shipping quickly and often
You are not your job
