I believe this is not the correct forum for this as it does not
concern development of Python language itself - you should post to
comp.lang.python. However solutions is relatively simply, try this:
list1,list2,list3,list4,list5,list6 = [ list(itertools.product(i,range(0,4)))
for i in itertools.combinations(criteria_list,2) ]
