Combat formulas in Python

Prototyping combat formulas in Python (v3), and I'm looking for a good way of storing a bunch of stats on different objects. Basically, i need an attacker object and a defender object, both of these will have the same types of stats (strength, dex, etc.) but used at different times.

Was thinking of using a dictionary so I can call eg EvadeRatingMagic on the object and get the correct value, but is there a better way?
