Every program works with data: names, ages, prices, messages. In Python you store that data in variables, and it comes in different types, mainly text (strings) and numbers. Understanding these basics is the foundation for everything else you will build. This guide assumes you have Python installed and can run a file. If not, read my guide on writing your first 10 lines of Python. Type each example yourself and compare the Output with what you see here.

When you open a website, send a message or run a scan, data travels across the network in small pieces called packets. Wireshark is a free program that lets you capture those packets and look inside them. Network engineers use it to fix problems, security teams use it to investigate incidents, and students use it to finally see how networks really work.
