Some pythonic advice needed

[andrew cooke]

i think you need something like the following (although you need to
extend it with scores, questions, etc.)

note that in my examples the two languages here are "digits" and
"words".  i use spanish and english just so that i have several
different words for the same value...!

andrew at tonto:~/src/python$ ./translations.py
translations of one are ['1', '1.0']
translations of 1 are ['one', 'un']
translations of two are ['2']
translations of 2 are ['two', 'dos']
known digits: ['1', '2', '1.0']
