True enough. Hadn't considered otherwise when I first whipped that off with
the first example (thinking/trying it out *before* posti

How about this?
a = ['a', 'b']
b = sorted(a) + ['whatever you want']
You could also do thi

Why are you trying to do that? It sounds ugly. Just sort the list with
the a's and b's. If you absolutely have to, you could make a class with
comparison methods

That line's assuming that the last element may also be found in arbitrary
locations in the list. If it's guaranteed that they're all contiguous at the
upper bounds, I'd just walk the list backwards until I found one that wasn't
matching rather than filterin
Apparently gmail hates me and my last response didn't get through:

l = sorted(lst[:-len(f)]) + f
Now, not 100% sure about efficiency over large sizes of a, but tha

Maybe
l = filter(a, lambda v: v == a[-1])
sorted(a[:-len(l)]) + l
?

more clearer, this is a more realistic use case:
['awefawef', 'awefawfsf', 'awefsdf', 'zz', 'zz',
'zz']
and the quantity of ''zz'' would be dynamic.
