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?

Thank you... That code looks elegant... I'll study it.
