An introduction to Python

This series introduces Python from the ground up – variables, functions, control flow, modules, and the rest. If you are new to programming or just new to Python, start here.

I’ve been writing code for decades, long enough to remember when languages felt deliberately awkward. Python is the opposite: readable, practical, and still capable enough for serious work.

Why Python? It turns up everywhere – web development, data analysis, automation, scripting, AI. It reads almost like English, which helps when you are learning. You do not need to memorise obscure syntax before you can do something useful.

We’ll work through the basics in order, with examples you can run yourself. Whether you want to automate boring tasks, crunch data, or build a web app, the same foundations apply.

These are tutorials, not lectures. I’ll share what works in practice, including the bits that tripped me up along the way.
