Pattern Matching Tutorial for Pythonic Code
Structural pattern matching is coming in Python 3.10. This article explores how to use it to write Pythonic code by searching for some of the best use cases for the match statement. Keep in mind that match is still in alpha, so, while unlikely, some things may still change before the final version of 3.10 is released.

The Weird Walrus
Python 3.8 introduced the world to the “walrus” operator, which is a colloquial term for the := operator used in the new assignment expressions. The expression a := 2 does two things: it assigns the value 2 to the name a and then returns the value 2. There’s something a little weird with assignment expressions, though. Try to execute a := 2 in a REPL and you’ll get a SyntaxError. But wrap the expression in parentheses (a := 2) and everything works like a charm. What? Why?

Python 3 Types in the Wild: A Tale of Two Type Systems
This academic paper from researchers at the Rensselaer Polytechnic Institute and IBM TJ Watson Research Center examines the MyPy and PyType tools and explores how Python developers use type annotations. The researchers collected over 70,000 Python GitHub repositories and found that only 2,678 had Python 3-style type annotations, most of which fail to type-check with either of the two tools. The paper’s third section is quite accessible and has a lot of interesting analysis.

Learn by Reading Code: Python Standard Library Design Decisions Explained
Along your Python learning journey, someone may have told you that a great way to level up your skills is to read code written by other people. That’s definitely true, but it’s not easy to find good sources of code to read and study. Python offers some advantages here because not only is the code open source, but the discussion surrounding design decisions is public, too.

For-Else: A Weird but Useful Feature in Python
Python for loops have an unusual feature: they support an else block that only executes if there is no break in the loop. The pattern isn’t used very often with the argument against it being that it is a bit weird and potentially difficult to understand. But there may be times when for/else makes sense. This article presents three situations where for/else is useful and argues that, in these situations, the pattern makes the code more readable.
