How else could it be done?

You could wrap it in a function, and reuse the code if you want to. That 
way you can imagine that it never happens ;-)

def cic(x,y);
     "Case insensitive compare"
     return x.lower() == y.lower()

But you cannot really do it any more efficient.

Forget your worries. It's probably just a case of premature optimisation.

Naturally there are special cases where you must do it more efficiently. 
But they would probably need to be solved based on the specific problem.
