Extracting item from list of tuples?

[Roy Smith]

I'm using httplib, and want to get the Location header from the 
response.  The getheaders() method gives you back a list of (name, 
value) tuples.  It would be a lot more convenient if it gave you back a 
dict, but it is what it is.

Anyway, I came up with:

    location = [t[1] for t in headers if t[0] == 'location'][0]

which works, but is getting on towards the cryptic end of things.  Is 
there a better idiom for this?
