Why does `getattr` not support consecutive attribute retrievals?

Question

class A(): pass

a = A()
b = A()

a.b = b
b.c = 1

a.b     # this is b
getattr(a, \"b\") # so is this

a.b.c   # this is 1   
getattr(a, \"b.c\") # this raises an Attrib         


        

Answer 1

What should return getattr('a.b', {'a': None}, 'default-value'}? Should it raise AttributeError or just return 'default-value'? That's why complex keys if introduced in getattr would make it obscure to use.

So, it's more natural to view getattr(..) function as get method of dictionary of object attributes.
