Transforming a str to an operator

[Duke Normandin]

Hey....

I'm a Python noob....

So far so good!

I've written the following:

num1 = raw_input('Enter the first number: ')
num2 = raw_input('Enter the second number: ')
op = raw_input('Select one of the following [+-*/]: ')
print 'The answer is: ', int(num1), eval(op), int(num2)
                                    ^^^^^^^^

How do I convert the contents of "op" from a string to an actual
arithmetic operator? eval() does not seem to be the answer. TIA!
