Readable syntax

Indentation matters.

Python uses indentation (not braces) to define blocks, making code clean and readable. It's designed to be beginner-friendly and reads almost like English.

Why Python

Readable syntax — indentation defines structure; code reads almost like English.
Huge library ecosystem — requests (APIs), pandas (data), boto3/azure-sdk (cloud), plus security tooling.
Cross-platform — the same script runs on Windows, Linux and macOS.
Everywhere in cyber — from automating log analysis to building tooling.

Python builds on core concepts and pairs with APIs & JSON for real automation across cloud and security work.
