Day 7/70 | Week 1 | 10 Weeks Challenge | My first Python CLI

Seven days ago, I started this challenge with a simple goal: learn by building.

Today, I completed my first Python CLI project — PyForge CLI.

What I built

PyForge is a simple command-line tool that brings together the Python concepts I learned during Week 1. Instead of writing small programs just to practice syntax, I wanted to build something that actually feels like a usable project.

Over the last 7 days, I worked through:

  • Python functions and data structures
  • Comprehensions, iterators and generators
  • Decorators
  • Object-oriented programming
  • Git and Linux basics
  • argparse and CLI development
  • Logging
  • Testing with pytest
  • Fixtures and code coverage
  • Python packaging

And finally, I put these pieces together into PyForge CLI.

What I learned

The biggest lesson wasn't a particular Python feature. It was learning how different concepts fit together when you're building an actual project.

Something that looks simple from the outside can involve quite a few decisions — project structure, error handling, testing, CLI arguments, packaging, documentation, and debugging.

Week 1 complete 🎯

One week ago, I was revisiting Python.

Today, I have a small CLI project that I can run, test, package and improve.

That's a pretty good start.

This is only Day 7 of my 70-day AI Engineer challenge.
