Question : Python: how to write this expression

Hi experts,

In the attached code, "oper" can be anything like '<', '>=', '==', etc. "exp_1" and  "exp_2" are all integer numbers.

I got an error for the 2nd line. The error was "SyntaxError: invalid syntax". Anybody knows how to fix it?

Thanks a lot.

            print "condition is true"
