Try this:
def __init__(self, operator, arg1, arg2):
self.operator = operator
self.arg1 = arg1
self.arg2 = arg2
Then you can do
x1 = Calculator('+', '1.0', '2.0')
x2 = Calculator('-', '666', '42')
or
x3 = Calculator(*sys.argv[1:4])
if you're really desperate to use the command line args.

Chris has already told you to give such accessor functions the flick,
but it should have done
return self.operator
