Re: Mapping operator tokens to special methods

I was starting to write a dictionary to map operator strings to their
equivalent special methods such as:

  '+' : 'add',
  '&' : 'and_'

The idea is to build a simple interactive calculator.
and was wondering if there is already something like this builtin?
Or is there a better way to do what I want?
There's not already a mapping builtin, but you should definitely look at 
the operator module:

py> import operator
py> ops = {'+':operator.add, '&':operator.and_}
py> ops['+'](3, 2)
5
py> ops['&'](3, 2)
2
