how to get the math operators strings from module `operator` in python
Question: Take `operator.add` for example:

    
    
    >>>import operator as op
    >>>op.add(1,2)       #means 1 + 2
    3
    >>>op.add.__name__
    'add'
    

I want sort of:

    
    
    >>>op.add.math_str
    "+"
    

Can I get all those math string `"+", "-", ">"...` module `operator` supported
runtime?

EDIT:

    
    
    >>> [eval(x) for x in [".".join(("op",x,"__doc__")) for x in dir(op)]]
    ['abs(a) -- Same as abs(a).',
     'add(a, b) -- Same as a + b.',
     'and_(a, b) -- Same as a & b.',
     'concat(a, b) -- Same as a + b, for a and b sequences.',
     'contains(a, b) -- Same as b in a (note reversed operands).',
     'delitem(a, b) -- Same as del a[b].',
     'delslice(a, b, c) -- Same as del a[b:c].',
     'div(a, b) -- Same as a / b when __future__.division is not in effect.',
     'str(object) -> string\n\nReturn a nice string representation of the object.\nIf the argument is a string, the return value is the same object.',
    

above code can list most operators strings, is that means I can list strings
with re module?

Thanks!


Answer: You can use the [following table from
tutorial](http://docs.python.org/library/operator.html?highlight=operator#mapping-
operators-to-functions) to build your own mappings dictionary only once and
then simply use it whenever you will need it.
