In Python, operators are special symbols, combinations of symbols, or keywords that designate some type of computation. You can combine objects and operators to build expressions that perform the actual computation. So, operators are the building blocks of expressions.

When choosing a tool for profiling Python code performance, should it focus on the CPU, GPU, memory, or individual lines of code? What if it looked at all those factors and didn’t alter code performance while measuring it? This week on the show, we talk about Scalene with Emery Berger, Professor of Computer Science at the University of Massachusetts Amherst.

In this tutorial, you’ll take a deep dive into parallel processing in Python. You’ll learn about a few traditional and several novel ways of sidestepping the global interpreter lock (GIL) to achieve genuine shared-memory parallelism of your CPU-bound tasks.

In this video course, you’ll learn about the various types of inheritance that you can use to write object-oriented code in Python. These include class inheritance, multilevel inheritance, and multiple inheritance, along with special methods and abstract base classes.

In this tutorial, you’ll learn all about object-oriented programming (OOP) in Python. You’ll learn the basics of the OOP paradigm and cover concepts like classes and inheritance. You’ll also see how to instantiate an object from a class.

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.

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.

Python uses object-oriented programming to group data and associated operations together into classes. In this video course, you’ll learn how to write object-oriented code with classes, attributes, and methods.

In August 2023, Python 3.12.0rc1 was released. Microsoft announced Python in Excel. The Python Software Foundation published its Annual Impact Report for 2023, and the Python ecosystem released new versions of several important projects, such as Django, Pydantic, and Flask.

What should you consider when picking a font for coding in Python? What characters and their respective glyphs should you check before making your decision? This week on the show, we talk with Real Python author and core team member Philipp Acsany about his recent article, Choosing the Best Coding Font for Programming.
