Array of functions, Pythonically

My parser has found an expression of the form CONSTANT_INTEGER
OPERATOR CONSTANT_INTEGER. I want to fold this into a single
CONSTANT_INTEGER.

The OPERATOR token has an intValue attribute, '+' == 0, '-'== 1, etc.
In C I'd put functions Add, Subtract, ... into an array and call
ArithmeticFunctions[ intValue ] to perform the operation. Would I
index into a list of functions in Python, or would IF/ELIF/ELIF ... be
the way to go?
