An Exploration of Python's Upcoming Match Statement
summary
Python 3.10’s match statement implements PEP-634 style structural patterns: literal and or patterns for alternatives, capture patterns (underscore as wildcard) that bind values, sequence unpacking with starred captures, and mapping patterns that require specific keys but ignore extra data. Class patterns do isinstance checks plus attribute subpatterns. Examples include an event dispatcher using attribute checks and a FizzBuzz implemented by matching a remainder tuple; demos run and behave like the spec says.
