python input for itertools.product
- by user364249
Looking for a way to simulate nested loops (or a cartesian product) i came across the itertools.product function.
i need a function or piece of code that receive a list of integers as input and returns a specific generator.
example:
input = [3,2,4] - gen = product(xrange(3),xrange(2),xrange(4))
or
input = [2,4,5,6] - gen = product(xrange(2),xrange(4),xrange(5),xrange(6))
as the size of the lists varies i am very confused in how to do that without the need of a lot of precoding based on a crazy amount of ifs and the size of the list.
also is there a difference in calling product(range(3)) or product(xrange(3))?
