Making Each Line of Code Efficient & Python In Excel
The Real Python Podcast
Python Updates, Safety Engineer Announcement, and Positive Progress on Security Front
The hosts discuss recent updates in the Python world, including the release of Python 3.12 RC1 and updates for other Python versions. They also announce the appointment of Mike Feidler as PIPI's new safety and security engineer, funded by AWS. Seth Larson shares positive progress on the security front for future Python development.
Are you writing efficient Python with as few lines of code as possible? Are you familiar with the many built-in language features that will simplify your code and make it more Pythonic? Christopher Trudeau is back on the show this week, bringing another batch of PyCoder’s Weekly articles and projects.
We discuss a recent post from Bob Belderbos titled “Make Each Line Count, Keeping Things Simple in Python.” We provide many of our favorite Pythonic examples and the language mistakes that we’ve learned from. We also share multiple resources to add to your learning path.
Microsoft has announced a limited beta program for Python in Excel. We dig into the current details, requirements, and potential use cases.
We cover several other articles and projects from the Python community, including a group of announcements from the Python Software Foundation, a showcase of the Polars DataFrame library, immortal objects in Python, a code image generator Python project, an MS Paint clone in the terminal, and a Django ORM cheatsheet.
Course Spotlight: Process Images Using the Pillow Library and Python
In this video course, you’ll learn how to use the Python Pillow library to deal with images and perform image processing. You’ll also explore using NumPy for further processing, including to create animations.
