Identify object class

[Nicolas Fleury]

Hi,
How do we quickly identify in Python if an object is of a specific
class *or* is of a class deriving directly or indirectly from that class?

BTW, don't you think this newsgroup has a lot of activity and it should
be time to make other newsgroups like comp.lang.python.windows, etc?

Thx and Regards,

Nicolas Fleury

You want the isinstance built-in function. Example:

if isinstance(obj,cls): do_whatever()

Good idea! I propose the following:

comp.lang.python.misc
comp.lang.python.gui
comp.lang.python.networking
comp.lang.python.dev
comp.lang.python.lisp-envy

her."

The volume goes up and down, I believe (through probably trending up).
The last two weeks have been up withthe x lisp threads.

The idea of division has come up occasionally for several years, but
never any agreement on what the split might be. Also, there are about
50 specialized Python mailing lists. Go to news.gmane.org which
gateways lists to its own newsgroups and look as gmane.comp.python.*.
