You could implement that ability in your own objects, but it's not
part of the protocol.
I forgot to mention generator expressions. This is an expression
(typically requiring parentheses) that evaluates to a generator
object. You can omit the parentheses if it's the only argument in a
call. For example:
>>> g = (chr(i) for i in range(65, 69))
>>> ", ".join(g)
'A, B, C, D'
>>> ", ".join(chr(i) for i in range(65, 69))
'A, B, C, D'
