Every concept in the language, in the order the course teaches it — with a working example, what it does, why you would use it, and the syntax detail that trips people up. The code window runs right in this page, so you can change an example, run it, break it, and see what happens without leaving the notes.
Fifteen units, 67 lessons, 153 concepts — printing and variables through functions, strings, lists, dictionaries and file input/output. Real Python runs in the browser, so every example is one click from running, and yours is one edit away.
Open NotesStructure and style, one concept at a time — elements, the box model, flexbox, grid, colour and type — with a live preview beside every example. Until this lands, CodeSnippetz has the playground and a full snippet library.
Coming SoonThe language that makes a page do something — variables, functions, events, the DOM, arrays and objects — each with a console you can type into. Until this lands, the Debugger covers JavaScript one concept at a time.
