hello there

I have searched the documentation in vein... :(

I would like to be able to

a) see all classes in the runing system

b) inspect all classse that can be found in pythonpath (to look for
classes not yet made instances of / loaded)
how to perform these simple tasks?

sincerely
Carlo

Well, then, I guess it's time to try an artery :-)
When I typed "python introspection" into Google, my first result was:

http://www-106.ibm.com/developerwork...y/l-pyint.html

which seems to be a nice introduction to the topic.

New style classes:

def allclasses():
klasses = { }
work = [ object ]
while work:
aType = work.pop()
if aType not in klasses:
klasses[aType] = None
work.extend(type.__subclasses__(aType))
return klasses.keys()

print allclasses()

Or for all classes, new and old:

import gc, types
for o in gc.get_objects():
if type(o) in (type, types.ClassType):
print repr(o)

b) inspect all classse that can be found in pythonpath (to look for
