^ is the XOR operator. Expected value is 6. You probably want pow (2,4). If you don't want to use eval, then the only solution is to implement the appropriate grammar parser. Have a look at pyparsing. Either you should take @fortran's approach, or you need to have your own parser and evaluator for custom operators.
