    I built a lightweight CLI log analyzer in Python while learning — here’s what I learned

    While learning Python I wanted to build something practical instead of small exercises, so I created a CLI tool called LogSnap.


    It analyzes log files locally and helps quickly detect problems without needing a full monitoring setup.


    What it does:
    • detects errors and warnings
    • shows surrounding context lines
    • filters by type
    • exports structured reports


    Why I built it

    I wanted a simple tool for quickly inspecting logs when debugging locally, without installing heavy stacks.


    What I learned building it
    • how to structure a CLI project properly
    • argument parsing design
    • clean separation of logic vs output
    • writing maintainable code early


    If anyone is curious or wants to try it:

    Feedback is always welcome 🙂
