what is the best language to do this in?

I have a set of data:
Sally has attribute A and attribute B
Bob has attribute D and attribute R
John has attribute S and attribute T
Melissa has attribute G and attribute M

etc.  There are over 300 names and 21 different attributes (let's call them A, B, ..., T, U) in varying combinations.

I want to pick out a set of 5 names with 2 attributes each that fit in a pattern of (for example) A,B,C,D,E,F,H,I,J,K

What's the best way to go about this?  I'm programming language neutral, though I do have some experience in bash, python and perl.  It would have to take input from a text file (either tab delimited or csv) and output which names to pick and what their attributes are.
