Are you ready for some exciting news? The latest version of our beloved language has been released and it’s packed with new features that will make coding easier than ever before! In fact, Python 3.9 is so awesome that even the developers behind it have decided to expedite its release due to security issues in previous versions.
But what exactly are these new features? Let’s have a better look:
1. Pure Positional Arguments Say goodbye to those ***** positional-only arguments! With Python 3.9, you can now use pure positional arguments without having to worry about keyword arguments getting in the way. This means less typing and fewer errors!
2. Match Case Statement If you’re a fan of switch statements (or “case” statements if you prefer), then you’ll love this new feature. The match case statement allows you to write more concise, readable code that is easier to understand at a glance. Plus, it’s just plain fun to use!
3. F-Strings with Assignment Expressions If you’re already using f-strings (formatted string literals) in your Python 3.8 code, then you’ll be thrilled to hear that they now support assignment expressions. This means you can assign a value and format it all in one line of code!
4. Improved Type Hinting If you’re using type hints (or “type annotations”) in your Python 3.8 code, then you’ll be happy to hear that they now support more advanced features like variable annotation and function return types. This makes it easier to write cleaner, more maintainable code!
5. New Math Functions If you’re a math whiz (or just enjoy playing with numbers), then you’ll love the new math functions in Python 3.9. These include the “math.isclose()” function for comparing floating-point values and the “math.comb()” function for calculating combinations of sets.
6. New Datetime Features If you work with dates and times, then you’ll be happy to hear that Python 3.9 includes some new datetime features like “datetime.fromisoformat()”, which makes it easier to parse ISO-formatted strings into datetime objects.
7. Improved Performance Finally, performance! According to the official Python documentation, Python 3.9 has been optimized for faster startup times and improved memory usage. This means your code will run faster and use less resources than ever before!
9 that we’re most excited about here at Casual Coding Central. We can’t wait to see what other cool stuff they come up with for future releases and we hope you enjoy using these new features as much as we do!
But before we go, something important: security issues. As mentioned earlier, Python 3.9 was expedited due to many security issues in previous versions. This means that the developers behind it have decided to only release security fixes for this series moving forward. So if you haven’t already upgraded to Python 3.9 (or a later version), we highly recommend doing so as soon as possible!
That’s all for now, happy coding!
