1. Python

Python is a high-level, interpreted language prized for clarity, batteries‑included libraries, and cross‑domain utility—from automation to APIs to data wrangling.

Why It's Important

It turns tedious admin work into tidy scripts, glues systems together, and accelerates troubleshooting. Less clicking, more doing.

How to Improve Python Skills

  1. Automate your own job: log rotation, report generation, inventory pulls, simple REST integrations.

  2. Write cleaner code: adopt a consistent style, type hints, and sensible project layouts with virtual environments.

  3. Expand your toolkit: standard library first, then popular packages (requests, pandas, pytest, Flask or Django when web creeps in).

  4. Think async where it counts: learn asyncio and when concurrency helps rather than hurts.

  5. Test and lint: unit tests, formatting, and linting keep scripts reliable as they grow.

  6. Read and refactor: revisit old scripts, simplify, measure speed, trim memory.

  7. Share code at work: internal repos, reviews, and small utilities others actually use.
