Merging dictionariesThere's a new operator "|" that can be used to merge two dictionaries.
See PEP 584 for more information: https://www.python.org/dev/peps/pep-0584/
Updating dictionariesAnother new operator "|=" will let you update dictionaries.
See PEP 584 for more information: https://www.python.org/dev/peps/pep-0584/
Removing the prefix and suffix of a stringThere are two new methods added to the str object to remove the prefix and suffix of the string.
We don't need to rely anymore on a much more fragile approach like slicing to do this.

Type hinting for built-in generic typesYou can now use list or dict built-in collection types as generics in the signature of a function.
This makes the code much more readable and explicit.

Python is now using a new parserWhy do you care? Well, this parser is much more flexible than the old one, and it will pay off dividends starting with Python 3.10.

There are many other changes and improvements. This includes new modules and several fixes across the language.
