Python foundations
Variables to functions, taught by building something real — so it sticks.
Your first 10 lines of Python
Variables, printing, and f-strings — the honest starting point. Ten lines, fully explained, nothing assumed.
Lists and loops: doing the same thing to many things
Working through a list of clients or matters without repeating yourself twice, ten times, or two hundred times — the pattern behind almost every real script.
Functions: write the logic once, reuse it forever
Turning a calculation you'd otherwise copy and paste — like a fee estimate — into a single reusable block you can trust every time.
Reading error messages without panic
What Python's red text is actually telling you — and how three common errors turn from scary to boring once you know the pattern.
Working with files: reading and writing safely
The with open(...) pattern you'll use every time Python needs to read a client list or write out a summary — and why it's built to fail safely.
The whole foundations track, on one page.
Variables to files — every pattern from these lessons on a single page you can bookmark or print. No sign-up, no catch.
