There's no such thing; you'd have to define it first. Are duplicates significant? Order? What you seem to want is easy enough: [a + b for a in 'hello' for b in 'world'] [...] > Cartesian products may be generally interesting for iterables: And maybe you want the result to be a generator: (a + b for a in 'hello' for b in 'world') New language features should be widely useful, and difficult or awkward to code in Python as it is. All-combinations-of-sequences is trivial to code and rarely needed. -- --Bryan -- http://mail.python.org/mailman/listinfo/python-list
