If you like building the part of an app nobody sees but everything depends on, APIs, databases and logins, this role is for you.
Builds the server side of web and mobile apps: APIs, databases and logins. Flask, FastAPI and Django run a large share of the web's APIs.
Take the lessons top to bottom. Each one opens with code you run, and ends with graded exercises that check your answer.
16 lessons every path shares. Skip the ones you already know.
Write your first Python program and print to the screen.
Numbers, strings, booleans — the building blocks.
Arithmetic, powers, the math module — Python as a calculator.
Slicing, methods, and f-strings — text manipulation done right.
Make decisions and repeat yourself — but only on purpose.
Loop until a condition fails. Bail out or skip with break/continue.
Collections of things, and how to walk through them.
Carve up lists and strings with [start:stop:step].
Two more collections: tuples are fixed, sets are unique.
Key → value pairs. The most important data structure in Python.
Empty things are False. `is` vs `==`. The infamous None.
The Pythonic ways to iterate — count, pair, sequence.
Bundle up logic so you can reuse it.
Lists of dicts, dicts of lists — modelling real-world data.
Filter and transform in one line — the Pythonic way.
Catch what could go wrong, recover gracefully.
16 lessons specific to this role.
Bundle state and behavior — the basics of OOP in Python.
How Python finds code. import, from, as.
Optional static typing — documentation that tools can check.
Parse and produce JSON — the universal data format.
GET, POST, headers, status codes, JSON — how Python talks to the web.
Routes, request handlers, JSON responses — the minimal web app.
Typed request/response models, auto-validation, auto-docs — modern Python APIs.
bcrypt for passwords, JWT for stateless sessions — real production auth.
A real database in a single file. Perfect for learning SQL end-to-end.
INNER, LEFT, RIGHT, FULL — with a concrete users-and-orders example.
SQLAlchemy Core tutorial: write database SQL with type-safe Python expressions, the foundation beneath the ORM.
Declare Python classes, get automatic CRUD, relationships, and lazy loading.
Python database migrations with Alembic and SQLAlchemy: evolve schemas safely with revisions, autogenerate, and an audit trail.
assert, parametrize, exceptions — the tests you'd actually write at work.
Beyond print() — structured logs, levels, handlers, and what real backends actually emit.
Fly.io, Railway, Vercel — take your FastAPI/Flask app live in one command.
Projects and workspace templates that fit this role. Publish the result to your portfolio page.
Finishing this path gives you the Python part of the job, with graded exercises and projects you can show. It is not, by itself, a qualification for the role.
