How to turn a list of tuples into a dictionary?

[mrstephengross]

Let's say I've got a list of tuples, like so:

( ('a', '1'), ('b', '2'), ('c', '3')

And I want to turn it into a dictionary in which the first value of
each tuple is a key and the second value is a value, like so:

{ 'a' -'1', 'b' -'2', 'c' -'3' }

Is there a way to do this with a single line of code? Currently, I'm
doing it like this:

tuples = ( ('a', '1'), ('b', '2'), ('c', '3')
d = {}
for option,value in tuples: d[option] = value

Thanks,
--Steve

I'd hand-code it manually, by linking a C extension. Or
dict( iterable ).

I'm not trying to be snide, but have you tried looking in the manual?

See http://python.org/doc/lib and look at the section about built-in
types, if you want to know things about tuples or dictionaries.

How about this?
d = dict(tuples)

d = dict(tuples)

Aha! I hadn't realized it could be so simple.
