I am implementing an application using XML-RPC, and would like to be
able to differentiate between multiple clients. The best way to do
this that I could think of would be to simply pass some unique
identifier along with each call over XML-RPC. However, this could get
to be a bit cumberso

Hi Dick,
because set(list) creates an unsorted collection without duplicate entrys
of the items in the list.
If you pass an empty list, the resulting set will also be an empty
collection.
A list containing an empty list evaluates non false, since it's not empty.
Maybe it helps you to compar

An empty collection is False. Anything else is therefore true

if (): -> false
