This is the input. What do you want the output to look like given
this input?
I can't really tell exactly what you mean by "all combinations", there
are different ways to combine sequences, and it doesn't sound like you
mean the formal mathematical definition of "combination".
My best guess is that you want something like this.
def all_union(seqs):
s = set()
for seq in seqs:
s.update(seq)
return s
