Problem breakdowns
Turn any vague task into small steps you can code one at a time.
Syntax gets you started; algorithmic thinking gets you hired. Learn to break problems into steps, search and sort like the standard library does, wield recursion without fear, and build an intuition for why some code is fast and some is hopeless.
Each lesson connects the Python concept to work you could automate, analyse or ship.
