Class Constructors & Pythonic Image Processing

<p>Do you know the difference between creating a class instance and initializing it? Would you like an interactive tour of the Python Pillow library? This week on the show, Christopher Trudeau is here, and he&rsquo;s brought another batch of PyCoder&rsquo;s Weekly articles and projects.</p> <p>We talk about the recent Real Python tutorial &ldquo;Image Processing With the Python Pillow Library.&rdquo; It walks you through manipulating, filtering, and creating images from scratch. </p> <p>Christopher shares an article about Python class constructors, exploring the two-step instance creation and initialization process.</p> <p>We also have a couple of discussions this week. The first is about contributing to open source projects. The second topic is about searching large codebases before adding features. </p> <p>We cover several other articles and projects from the Python community, including the counter-intuitive rise of Python in scientific computing, preparation for interview questions, a project for adding pointer hell to Python, and a fast and powerful graphical user interface tool kit for Python with minimal dependencies.</p> <div class="alert alert-primary" role="alert"> <p><strong>Spotlight:</strong> <a href="https://realpython.com/courses/python-vs-javascript-for-python-devs/">Python vs JavaScript for Python Developers</a></p> <p>Python and JavaScript are two of the most popular programming languages in the world. In this course, you&rsquo;ll take a deep dive into the JavaScript ecosystem by comparing Python vs JavaScript. You&rsquo;ll learn the jargon, language history, and best practices from a Python developer&rsquo;s perspective.</p> </div> <p>Topics:</p> <ul> <li>00:00:00 &ndash; Introduction</li> <li>00:02:18 &ndash; Image Processing With the Python Pillow Library</li> <li>00:11:10 &ndash; The Counter-Intuitive Rise of Python in Scientific computing</li> <li>00:17:15 &ndash; 20 Python Interview Questions</li> <li>00:25:48 &ndash; Sponsor: FusionAuth</li> <li>00:26:25 &ndash; Python Class Constructors: Control Your Object Instantiation</li> <li>00:31:17 &ndash; Do You Contribute to Open Source Projects?</li> <li>00:42:43 &ndash; Video Course Spotlight</li> <li>00:44:08 &ndash; How To Search Large Codebases Before Adding a Feature?</li> <li>00:49:34 &ndash; pointers.py: Bringing the Hell of Pointers to Python</li> <li>00:52:16 &ndash; DearPyGui: A fast and powerful Graphical User Interface Toolkit for Python</li> <li>00:57:11 &ndash; Thanks and goodbye</li> </ul> <p>Topic Links:</p> <ul> <li><a href="https://realpython.com/image-processing-with-the-python-pillow-library/">Image Processing With the Python Pillow Library</a> &ndash; Learn how to use the Python Pillow library to deal with images.
