Trying to generate a list of the subclasses of C

[Charles Krug]

List:

I have this:

# classC.py

class C(object): pass

class D(C): pass

class E(C): pass

def CSubclasses():
    for name in dir(): pass

I'm trying to create a list of all of C's subclasses:

import classC

print C
aList = []
for name in dir(classC):
    print name,
    try:
        if issubclass(classC.__dict__[name], C):
            print classC.__dict__[name]
        else:
            print
    except TypeError:
        print

Which gives me this:

<class '__main__.C'>
C
CSubclasses
D
E
__builtins__
__doc__
__file__
__name__

However when I do this from the command line:

>>> issubclass(D,C)
True

but

>>> issubclass(classC.__dict__['D'], C)
False

So my approach is flawed.

The end result I'm after is an automatically generated dictionary
containing instaces of the subclasses keyed by the subclass names:

{'D':D(), 'E':E(), . . . }

I can see the information I need in the module's __dict__ and by using
the dir() method, but I'm not having much success extracting it.
