What is Python 3.9 and why should you download it?
Python 3.9 is the latest stable release of Python as of October 2020. It comes with many new features and improvements that make it faster, easier, and more powerful than ever before.
Some of the new features in Python 3.9 are:
Union operators in dict: You can now merge or update dictionaries using the and = operators, which are more concise and readable than the .update() method.
Type hinting generics in standard collections: You can now use built-in collection types such as list, dict, set, etc., as generic types in type annotations, without importing them from typing module.
String methods to remove prefixes and suffixes: You can now use .removeprefix() and .removesuffix() methods on strings to remove unwanted characters from the beginning or end of a string.
Support for the IANA time zone database in the standard library: You can now use the zoneinfo module to access accurate and up-to-date information about time zones around the world.
New parser based on PEG: Python now uses a new parser that is based on Parsing Expression Grammar (PEG), which is more flexible and maintainable than the previous one based on LL(1) grammar. This allows for more syntactic features and better error messages in the future.
These are just some of the highlights of Python 3.9. There are many more changes and enhancements that you can explore in the official release notes.
Downloading Python 3.9 will give you access to these new features and improvements, as well as ensure that your code is compatible with the latest standards and best practices. You will also be able to use the latest libraries and frameworks that depend on Python 3.9.
