:pep:`448` -- Additional Unpacking Generalizations
PEP 484 - Type Hints
--------------------
This PEP introduces a provisional module to provide these standard
definitions and tools, along with some conventions for situations
where annotations are not available.
For example, here is a simple function whose argument and return type
are declared in the annotations::
def greeting(name: str) -> str:
return 'Hello ' + name
The type system supports unions, generic types, and a special type
named ``Any`` which is consistent with (i.e. assignable to and from) all
types.
