Scapy is a Python module and interactive program for low-level network programming that attempts to make it easier without abstracting away the technical details. This project is fairly prominent in cybersecurity space and used for things like exploit development, data exfiltration, network recon, intrusion detection and analysing captured traffic. Scapy integrates with data visualisation and report generation tooling for presenting the results of your research to bug bounty program or during the meeting with customer or management. The foundational idea for Scapy is proposing a Python-based domain specific language for easy and quick wire format management.
Whether I’m teaching new Pythonistas or long-time Python programmers, I frequently find that Python programmers underutilize multiple assignment.
Multiple assignment (also known as tuple unpacking or iterable unpacking) allows you to assign multiple variables at the same time in one line of code. This feature often seems simple after you’ve learned about it, but it can be tricky to recall multiple assignment when you need it most.

Emacs shortcuts (known as ‘key bindings’) can seem ridiculous to beginners. Some Emacs users even argue you should change them as soon as you start using Emacs.
They are wrong. In this post, I’ll describe the logic behind the Emacs key bindings. Not only will you be closer to passing the guru test, but you might even find you like some of the defaults!
