Question

I have a list of 2-tuples like this:

l = [(\'a\', 1), (\'b\', 2)]

and I want to be able to map this onto a dictionary object, so that I can

Answer 1

Why not just do this:

d = dict(l)

Also, to answer your question, your solution is failing because y (which is a 2-tuple) has no method update, since it's not a dict. Thankfully, what you're doing is built right in.
