I see no benefit for a generator here as the whole list mus be build for
sorting anyway.  If you still want return an iterable here it could be
written this way:

class Something(object):
    def iter_entries(self):
        return iter(sorted(self._data.keys()))

Just leave out the `iter()` call to return a sorted list.

If you want to make `Something` objects iterable over the sorted keys,
change the method name to `__iter__()`.  Then you can use `Something`
objects like this:

something = Something()
# Puts some entries into `something`.
for entry in something:
    print entry
