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:
