3.10
Python Language Reference
The Python Language Reference is the official, authoritative specification of the Python programming language.
Python 3.10 was released in October 2021. It introduced the following new language features:
- structural pattern matching
- parenthesized context managers
- new typing features (union types as
X | Y, explicit type aliases, and parameter specification variables)
See What’s New In Python 3.10 for more details.
We have not (yet) cross-referenced this language specification with our misconceptions. To find misconception by language specification section, pick one of the cross-referenced specifications.
