It means "n choose k", or in this case, "a choose b" .
Binomial coefficient ? (also, see combination )
Combination.
Combination is the first thing that comes to mind...but without context, there are probably other meanings for the same notation .

Using Python, how would I go about reading in (be from a string, file or url) a mathematical expression (1 + 1 is a good start) and executing it?
Aside from grabbing a string, file or url I have no idea of where to start with this.
