What you are building
Wordwell is a dictionary app you assemble in twelve short stages. The teaching stack is wxPython (Python 3, wxPython, JSON word list). By the end you should understand the shell, the data you persist, and the everyday workflows people expect from this kind of app.
wxPython gives native-feeling widgets on multiple platforms. A dictionary is a focused search + detail UI.
Typeahead list plus definition pane teaches filtering large lists without a full database server.
Work in order. Early folders are intentionally small so you can see the window (or server) boot before features pile on. From the data-layer part onward, each snapshot should still run after you install dependencies.
Read the goal, clone the matching GitHub folder, run it, then skim the code against the notes below. If something fails, fix the run path first—most “bugs” on day one are the wrong directory or a skipped install.
Parts in order
Each chapter below is one checkpoint. Open a part when you are ready for that feature—not all at once.
