Pampy is a small (~150 line) Python library providing pattern matching, letting you match values against literals, types, tuples, lists, dicts, and wildcards with lambda handlers. It supports nested structures, HEAD/TAIL list matching, and REST arguments.
Use cases
- add pattern matching to python code
- match nested dicts and lists in python
- write a lisp interpreter in python
- replace if-else chains with pattern matching
- destructure lists with head and tail in python
When to choose
- you want readable, functional-style dispatch over data structures in Python 3
- you need to match deeply nested lists, tuples, or dicts concisely
When to avoid
- you're on Python 3.10+, which has native structural pattern matching (match/case)
- you need maximum performance in hot code paths
