Better way to do this?

[PRC]

Hi folks,

I have a tuple of tuples, in the form--> ((code1, 'string1'),(code2,
'string2'),(code3, 'string3'),)

Codes are unique. A dict would probably be the best approach but this
is beyond my control.

Here is an example:
>>>pets = ((0,'cat'),(1,'dog'),(2,'mouse'))

If I am given a value for the code I need to retrieve the string
representation. The value is guaranteed to be valid.

This is what I came up with...

>>>value=1
>>>[ pet for code, pet in pets if value==code ][0]
'dog'

It does the job, I was just curious if there was a better way to do
it.
