How to give a custom object instance a type name ?

[Graeme Matthew]

Hi all, quick one,

I hope I am explaining this properly, I am wanting to do some introspection
on custom object instances, for example:

import md5[color=blue][color=green][color=darkred]
>>> m = md5.new()
>>> type(m)[/color][/color][/color]
<type 'md5.md5'>

I can at least test here by doing something like if type(m) == 'md5.md5':


Here is a custom Dispatcher class that I have written
[color=blue][color=green][color=darkred]
>>> from BI.System.Contr oller.Dispatche r import Dispatcher
>>> x = Dispatcher()
>>> type(x)[/color][/color][/color]
<type 'instance'>

How do I get the same as with instance 'm' above where the type displays the
actual object instance name, however my
custom dispatcher instance is just a generic 'instance', is there some
builtin where this is set ?

many thanks

Graeme

>>> x.__class__.__n ame__[/color][/color][/color]

x.__class__.__n ame__
'Dispatcher'[color=blue][color=green][color=darkred]

how about doing this instead:

isinstance(m,md 5.md5)
[color=blue]

isinstance(x,Di spatcher)

otherwise if you _really_ need the name - just do as some others indicated.

You could also use new-style classes, btw.
