 How can i write this function Cprod (Cartesian Product) simply?
                  (writing this out: itertools.product([0, 1], repeat=N
)
 The value can be a list or a Tuple.
                  cprod([0, 1], 1) => ((0) (1))
                  cprod([0, 1], 2) => ((0,0) (0,1) (1,0) (1,1))
   This works:
     def cprod(x, c):
         if c==1: return [[i] for i in x]
         Sub= cprod(x, c-1)
         return [i  for F in x   for i in [[F]+R for R in Sub]]
  ---------- Is there another way to write [F]+R ???
                 Other ways to improve it?
