@Frank, @Wyatt: Mostly because I’ve been trained, from the people and code I’ve worked with, to avoid lambdas 99% of the time, giving preference to named function definitions. So, what I used to use was:

@property
def abc(self):
    return self._abc

Using attrgetter makes it easy to turn that into a one-liner, without having to use lambda :) Plus, as Alexander points out, the name “attrgetter” certainly tells you pretty directly what’s going on.

Just for fun, how about this:

uri = property(lambda self: self._uri)

Why not simply use property(lambda self: self._uri)?

Very neat! I’ve always done:

uri = property(lambda x: x._url)

which though terse isn’t as clear as attrgetter!
