In Python you can write something like this:

a = (1, 2, 3)
b = {'foo': 'bar'}
my_function(*a, **b)

Is there a specific term for what happens in the last line with a and b and, if yes, what is it? It's not "destructuring" I suppose. And "variable expansion" sounds wrong too.

It's [*"unpacking"*](https://docs.python.org/2/tutorial/controlflow.html#unpacking-argument-lists). – jonrsharpe May 25 '16 at 06:19
