If you like breaking software on purpose so real users never have to, and writing tests that catch the next bug, this role is for you.
Makes sure software works by writing automated tests instead of clicking through by hand. pytest is one of the most popular test frameworks, and Python scripts drive API and UI tests.
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.
10 lessons specific to this role.
Bundle state and behavior — the basics of OOP in Python.
How Python finds code. import, from, as.
Parse and produce JSON — the universal data format.
GET, POST, headers, status codes, JSON — how Python talks to the web.
assert, parametrize, exceptions — the tests you'd actually write at work.
Shared setup, dependency injection, monkeypatch — how real test suites stay fast.
pdb, breakpoint(), tracebacks — beyond print-statement debugging.
Turn a Python script into a proper command-line tool with args, flags, and --help.
Beyond print() — structured logs, levels, handlers, and what real backends actually emit.
The 15 git commands you actually use. Branching, merging, rescuing yourself.
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.
