Pattern matching in Python

Pattern matching in Python: "Pattern matching is most powerful when it enjoys first-class support in a language. In addition to succinct syntax, this affords you the ability to integrate pattern matchers with control constructs, allowing conditional execution of code based on various patterns. It also may give you a degree of composability not possible otherwise. For example, Erlang has not only a case statement, but allows for clauses in functions, so that pattern matching is done on the arguments of functions with the same name and arity."
