check if object is number

[Mark English]

Not sure if anyone's mentioned this yet, but just in case they haven't:
---- Start bit o' Python ----
>>> import operator
>>> operator.isNumberType(1)
True
>>> operator.isNumberType(1.01)
True
>>> operator.isNumberType('a')
False
>>> operator.isNumberType('1')
False
---- End bit o' Python ----
Haven't looked at the implementation (or the docs for a while) but for
everyday usage (not that I do this everyday) it's all the implementation
I need.
