Attribute getters in python

Question

I vaguely remember learning about some sort of built-in function that would do the equivalent of

f = lambda x: x.attr

Am I just imagining this or does such a thing exist?

getattr(obj, 'attr')

will get the attribute attr from obj, or raise AttributeError if it doesn't exist. You can also supply a default value:

getattr(obj, 'attr', None)

in which case the default will be returned instead of raising an exception if the attribute can not be found on the object.
