Recommended way to add a key-value-pair given as tuple to a dict?

Question

It feels like I'm just missing the obvious but.. how do I add a value to a dict if I'm given a key-value-tuple?

def foo():
    # magic
    return key, value

d = {}
d.update((foo(),))

Isn't there something like d.add(foot()) ?

I hope I'm just in need of some coffee..

Answer 1

this works but I don't know this is recommended.

d.update(dict([foo()]))
