Introspect current module to get classes

[Troy Melhase]

Hi Edmund:

Put the following code in a module named "look_at_me.py":


class A(object):
    pass

class B(A):
    pass

class C(A):
    pass

def list_local_classes():
    this_mod = __import__(__name__)
    return [val for val in this_mod.__dict__.values()
                if isinstance(val, type)]

local_classes = list_local_classes()



Then fire up your python interpreter and try it out like this:

troy at marchhare tmp $ python
Python 2.2.2 (#1, Mar 19 2003, 01:56:47)
[GCC 3.2.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import look_at_me
>>> look_at_me.local_classes
[<class 'look_at_me.A'>, <class 'look_at_me.C'>, <class 'look_at_me.B'>]
>>>


You'll probably want to adjust the "if isinstance" check to your meet your
needs.  Hope this helps,
