One more thing regarding Git:

You'll likely want to keep your main branch functional at all times, so you would normally wait with your commit and push until a feature is ready. This wouldn't mix well with switching machines at random times.

That's where branches come in handy: create a feature branch, commit and push as often as you want. If the feature doesn't happen to work out, just delete the branch. When the feature is ready, merge the branch into the main branch. There even is an option to squash commits into a single one when merging, so you don't have to keep the whole commit history you created in the feature branch.

Aber der Kaffee nicht, glaube ich.

I'd pay to watch the top-right fight.

Same! But not just the coffee. It's the entire breakfast I'm already excited about! I'll feast!

The irony that you use a device that's way more expensive than OP's lovely project to write this comment...

I tried getting used to cookiecutter with one of the well-known Python project templates several times, but I always found that those are way too much boilerplate for my simple needs.

So I stick with copying and modifying my previous project every time, and even that doesn't make things much easier because I always find something I should do different next time, so in the end no project is completely like its predecessor.

Let us know what you'll come up with!
