Free, interactive Python tutorial covering basics through advanced topics like generators, decorators, and regex — runs entirely in the browser
Visit LearnPython.org →LearnPython.org runs entirely in the browser — each short lesson pairs an explanation with an editable code panel that executes instantly, no local setup required. Coverage runs from absolute basics through more intermediate topics like generators, decorators, closures, and regular expressions, organized as bite-sized, self-contained pages rather than one long course.
The interactivity makes it a good fit for learning by doing rather than watching, though it’s lighter on project-based practice than something like Exercism — worth pairing the two if you want both concept coverage and real coding reps.
