| Pros | Cons | |------|------| | Well-structured, day-by-day plan | Last edition covers Python 3.4/3.5 – missing f-strings, pathlib , asyncio , newer typing features | | Good for absolute beginners | “21 days” pacing is unrealistic for most learners | | Hands-on examples | Some libraries/tools mentioned are outdated (e.g., urllib2 instead of requests ) |
