Lists of lists and tuples, and finding things within them

[Michael B. Trausch]

I have a program that keeps some of its data in a list of tuples.
Sometimes, I want to be able to find that data out of the list.  Here is
the list in question:

[('password01', 'unk'), ('host', 'dragonstone.org'), ('port', '1234'),
('character01', 'Thessalus')]

For a regular list, I could do something like x.index('host') and find
the index of it, but I don't know how to do this for a tuple where the
data item isn't known in advance.  For example, I want to get the "host"
entry from the list above; but I can only retrieve it if I know what it
contains (e.g., x.index(('host', 'dragonstone.org'))).

Is there a better way to do this than a construct similar the following?

for key, value in x:
    if key == 'host':
        print value

Thanks in advance!
