A History of Python Versions and Features - Real Python

"This course gives you a direct, practical overview of how Python has evolved-what changed in each major version, why it matters, and how to use the features that define modern Python. You'll see both the historical context and hands-on code, so you understand not just what changed, but why and how to use it today. In this course, you'll learn: Key new features introduced in every major Python version, starting from early Python 1 up to Python 3.14"

"The story behind pivotal changes, like list comprehensions, exception handling, the with statement, defaultdict, and the transition from Python 2 to Python 3 Hands-on use of modern Python tools: f-strings, dataclasses, the walrus operator (:=), match/case structural pattern matching, and new types like enum and pathlib How to leverage improvements in each Python release for cleaner, faster, and more maintainable code"

Coverage spans key features introduced in every major Python version from early Python 1 through Python 3.14. Explanations cover the origins and reasons for pivotal changes such as list comprehensions, exception handling improvements, the with statement, defaultdict, and the migration from Python 2 to Python 3. Practical examples demonstrate modern Python tools including f-strings, dataclasses, the walrus operator (:=), match/case structural pattern matching, enum, and pathlib. Guidance shows how to apply release-by-release improvements to write cleaner, faster, and more maintainable code. Upcoming-release topics include t-strings and REPL enhancements. Downloadable resources accompany the material.
