I am expecting 'a' and 'b' wil= l be not longer than 10 char's long.... I tried making x =3D 'zzzzzzzzzzzzz= zzz' and believe it or not, this appears FIRST on the sort!!! >=20 > >=20 >=20 > >=20 >=20 > >=20 >=20 > > It appears last when I run the code. >=20 > >=20 >=20 > >=20 >=20 > >=20 >=20 > > To answer your question, though, if you want to force x to be last, >=20 > >=20 >=20 > > then I suggest removing it from the list and then appending it to the >=20 > >=20 >=20 > > end. I am thinking if it is helpful to preprocess an arbitrary list first into some set of unique ordered elements before a sort.=20 Anyway lists are passed by references to functions in python.=20
