Getting Involved in Open Source & Generating QR Codes With Python

Have you thought about contributing to an open-source Python project? What are possible entry points for intermediate developers? Christopher Trudeau is back on the show this week, bringing another batch of PyCoder’s Weekly articles and projects.

We discuss a recent article by Stefanie Molin called “5 Ways to Get Started in Open Source.” Christopher shares his experience with suggesting features and potential bug fixes. We talk about common entry points for beginners and provide additional resources.

We cover a recent Real Python tutorial about creating QR codes with Python. The tutorial introduces the library Segno and tours the features. By working through the examples, you’ll be ready to build a QR code project yourself.

We also cover several other articles and projects from the Python community, including a couple of release announcements, an introduction to Python’s functools module, Hatch as an alternative for packaging, options for when NumPy is too slow, a simple diceware generator project, and a collection of machine learning recipes.

  • Generate Beautiful QR Codes With Python – In this tutorial, you’ll learn how to use Python to generate QR codes, from your standard black-and-white QR codes to beautiful ones with your favorite colors. You’ll learn how to format QR codes, rotate them, and even replace the static background with moving images.
  • Introduction to Python’s Functools Module – This article introduces you to the functions in Python’s functools module with real-world examples to help show you how and when to use each feature.
  • Switching to Hatch – Oliver used Poetry for most of his projects, but he recently tried out Hatch instead. This blog post covers what it took to get things going and what features he used, including how he ditched tox.
  • When NumPy is too slow – NumPy is typically faster than plain Python for numeric calculations. What should you do when you find your NumPy-based code is too slow?
