Error Handling in Python: try, except and Best Practices
How to handle errors in Python so failures are visible and recoverable: the exact order try, except, else and finally run in, why a broad except hides bugs, designing custom exceptions, chaining with raise from, logging tracebacks, and retrying only what is worth retrying.
Datetime in Python: Working with Dates and Times
The datetime rules that prevent real bugs: why naive and aware datetimes cannot be compared, how to attach and convert time zones with zoneinfo, parsing ISO strings and custom formats, formatting for people, and why adding one day is not always 24 hours.
Building REST APIs with Python: A Practical Guide
The design decisions behind a REST API that other programs can depend on: resource URLs, what GET, POST, PUT and DELETE promise, the status codes that matter, validation at the boundary, one error format, and pagination. Shown with a small Flask API exercised through its test client.
Flask vs FastAPI vs Django: Which to Choose in 2026
Flask, FastAPI and Django compared on what actually differs: what each includes out of the box, how validation, async and data access work, the same small endpoint written in all three, and which one fits a content site, a JSON API, an ML service or an internal tool.

Three mini projects are scoped that way here, a weather and bike-rental explorer, a safe file organiser and a habit tracker, with each Saturday core built and run.
