My Top 5 - Python 3.11’s best new features
On October 24, 2022, Python 3.11 was released. Python’s most recent version is faster and more user-friendly. It is now ready for use after months of development.
Developers are encouraged to test this latest version on non-production code to ensure that it works with their programs and to determine whether their code will benefit from the performance improvements.
Here is a summary of Python 3.11’s most important new features and what they signify for Python developers.
1. Faster execution of code:
Speed enhancement is the first notable modification that will delight data scientists.
Python is far from the fastest programming language available. That is about to change.
Python 3.11 is approximately 1.25 times quicker than Python 3.10, according to the official Python benchmark suite, and can occasionally be up to 60% faster. Keep in mind that this speedup is an overall measurement. While many objects simply move little or about the same speed as before, some things move substantially quicker. The fact that these enhancements are free is still their best feature. Python scripts can benefit from Python 3.11’s speedups without any code modifications.
2. Improved error information:
More detailed error messages are a feature of Python 3.11 that is also instantly helpful.
3. Typing enhancements:
Since Python 3.5, type-hinting features have grown steadily in number, making it simpler to maintain and analyze larger codebases. There are various new type-hinting additions in Python 3.11.
4. Transforms for Dataclass:
Libraries with dataclass-like semantics cannot describe their behavior to type checkers in Python. The “typing.dataclass_transform” decorator is now available in 3.11 to indicate how a given function, class, or metaclass acts as a dataclass.
5. Self Type:
Using “typing.Self”, in Python 3.11, you can now annotate the return value of a class method as just “Self.”
