Have you ever used code to help explain a topic? How can Python scripts be used to understand the intricacies of access control? This week on the show, Christopher Trudeau is here, bringing another batch of PyCoder’s Weekly articles and projects.

Episode Sponsor:

Christopher talks about an article that explores the evolution of access control by reimplementing the concepts with Python scripts. The experiment moves across the various access forms, starting with control lists, roles, and attributes, then ending with purpose-based access control (PBAC).

We also cover a post about how to create dangerous pickles. We discuss where malicious code can hide within the serialization process and how decompiling code can be an education tool.

We share several other articles and projects from the Python community, including command line interface (CLI) creation with argparse, HTML and CSS for Python developers, a Python packaging user survey, a visual Python Tkinter GUI creator, a PyScript-based data visualization cookbook, and a project for writing functional test helpers in Django.

  • HTML and CSS for Python Developers – There’s no way around HTML and CSS when you want to build web apps. Even if you’re not aiming to become a web developer, knowing the basics of HTML and CSS will help you understand the Web better. In this tutorial, you’ll get an introduction to HTML and CSS for Python programmers.
  • Evolution of Access Control Explained Through Python – Sometimes, writing code can help you explore and understand concepts. This article shows a history of access controls in software, using Python scripts to reimplement the ideas.
  • Dangerous Pickles – A light introduction to the Python pickle protocol, the Pickle Machine, and the construction of malicious pickles. Learn why your code shouldn’t trust arbitrary serialized objects, and discover the dangers of pickle-bombs.
  • Building Command Line Interfaces With argparse – In this step-by-step Python video course, you’ll learn how to take your command line Python scripts to the next level by adding a convenient command line interface that you can write with argparse.
