You could overload __getattr__ (might have to play around a bit to make sure
any possible AttributeError's look right, but the basic idea is here)
class A(object):
# ...
def __getattr__(self, name):
try:
return object.__getattribute__(self, name)
except AttributeError:
if '.' in name:
attrs = name.split('.')
first = object.__getattribute__(self, attrs[0])
return getattr(first, '.'.join(attrs[1:]))
raise
>>> a = A()
>>> a.b = A()
>>> a.b.c = A()
>>> a.b.c.d = A()
>>> getattr(a, 'b.c.d')
<__main__.A object at 0x67f50>

Hello,
lets assume i have some classes:
class A(object):
def __init__(self):
b = B()
class B(object):
def __init__(self):
c = C()
class C(object):
def __init__(self):
pass
and now i wanna do something like this:
a=A()
c=getattr(a, 'b.c')
I know this doesn't work, but what can i do to get this or a similar
functionality to get it work for this sample and for even more nested
classes?
Kind regards,
Andre
