Structural pattern matching is a powerful control flow construct invented decades ago that’s traditionally used by compiled languages, especially within the functional programming paradigm. Most mainstream programming languages have since adopted some form of pattern matching, which offers concise and readable syntax while promoting a declarative code style. Although Python was late to join the party, it introduced structural pattern matching in the 3.10 release. Getting to Know Structural Pattern Matching Before taking advantage of structural pattern matching in your […]

In Python, type hinting is an optional yet useful feature for making your code easier to read, reason about, and debug. With type hints, you let other developers know the expected data types for variables, function arguments, and return values. As you write code for applications that require greater flexibility, you may need to specify multiple return types to make your code more robust and adaptable to different situations. You’ll encounter different use cases where you may want to annotate […]

Python has several pieces of syntax that are syntactic sugar. This sugar is syntax that isn’t strictly necessary but gives Python some of its flavor as a readable, beginner-friendly, and powerful language. In this tutorial, you’ll explore some of Python’s most used pieces of syntactic sugar. In practice, you already use most of these pieces of syntax, as they include many well-known Pythonic constructs. As you read on, you’ll see how Python works under the hood and learn how to […]
