The first line the computer takes seriously.
Ten units along one shift at a bakery. You write, the interpreter answers — from the note on the door to the mould at the end.
Free · a phone keyboard opens the page, but the exercises want a computer.

The shift
One shift at a bakery, not a manual's table of contents
There is a shop, there is a shift, and there are people who need a note on the door and a notebook that survives closing time. Each unit hands you a tool at the moment the shop already needed it.
Who works this shift
Three names, so we don't say "the user" all day
The one who speaks first: the print, the name tag, the name on the record.
When a gesture repeats, she asks for a name for the procedure — and a file that doesn't die at closing time.
A random draw, an argument on the command line, a package that came ready. The shop doesn't make everything from scratch.
What you need
Three things, and none of them is the cloud
A plain editor
VS Code, Vim, Notepad. Word and Docs hide formatting inside the file.
note.py · utf-8
A terminal in the folder
The command only finds the file if you are in its folder. You don't type the $.
$ python note.py
Unit 1 is the door. The rest of the shift is yours, once.

Pay once. The whole shift stays on your account, with nothing billed monthly.
Estimate to finish with the exercises (or ~12–15 h at minimum). At 1 h/day: about 3–4 weeks.
The paid lessons follow the same thread as unit 1: bakery, terminal and exercises with hints.
