Getting Involved in Open Source & Generating QR Codes With Python
Show notes
<p>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.</p> <p>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. </p> <p>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.</p> <p>We also cover several other articles and projects from the Python community, including a couple of release announcements, an introduction to Python’s <code>functools</code> 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.</p> <div class="alert alert-primary" role="alert"> <p><strong>Course Spotlight:</strong> <a href="https://realpython.com/courses/caching-python-lru/">Caching in Python With <code>lru_cache</code></a> </p> <p>Caching is an essential optimization technique. In this video course, you’ll learn how to use Python’s <code>@lru_cache</code> decorator to cache the results of your functions using the LRU cache strategy. This is a powerful technique you can use to leverage the power of caching in your implementations.</p> </div> <p>Topics:</p> <ul> <li>00:00:00 – Introduction</li> <li>00:02:04 – 2023 Django Developers Survey</li> <li>00:02:36 – Python 3.12.0 Release Candidate 2 Available</li> <li>00:03:04 – Pandas 2.1.0 Released</li> <li>00:03:27 – PEP 713: Callable Modules - Rejected</li> <li>00:04:52 – Generate Beautiful QR Codes With Python</li> <li>00:10:17 – Introduction to Python’s Functools Module</li> <li>00:14:00 – Switching to Hatch</li> <li>00:20:08 – Video Course Spotlight</li> <li>00:21:27 – When NumPy is too slow</li> <li>00:26:31 – 5 Ways to Get Started in Open Source</li> <li>00:42:28 – nodice-cli: A simple diceware generator with no dependencies</li> <li>00:44:32 – ML-Recipes: Collection of Machine Learning Recipes</li> <li>00:47:00 – Thanks and goodbye</li> </ul> <p>News:</p> <ul> <li><a href="https://www.djangoproject.com/weblog/2023/sep/05/2023-django-developers-survey/">2023 Django Developers Survey</a></li> <li><a href="https://pythoninsider.blogspot.com/2023/09/python-3120-release-candidate-2-now.html">Python 3.12.0 Release Candidate 2 Available</a></li> <li><a href="https://pandas.pydata.org/docs/whatsnew/v2.1.0.html">Pandas 2.1.0 Released</a></li> <li><a href="https://discuss.python.org/t/pep-713-callable-modules/26127/86">PEP 713: Callable Modules - Rejected - PEPs - Discussions on Python.org</a></li> </ul> <p>Show Links:</p> <ul> <li><a href="https://realpython.com/python-generate-qr-code/">Generate Beautiful QR Codes With Python</a> – 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.
