List Functions

Enumerate Function

Description:
Returns a list by enumerating all the combinations formed by taking one element from each list at a time.
For example, in a situation where you have two products that come in 3 sizes, you can use this function to get a list of all the possible combinations (see below).
In general if n number of lists (L1, L2, ... Ln) are passed to Enumerate, the result will be a list of lists, where each inner list is of length n, and the outer list will have length which is count(L1) * count (L2) * ... * count(Ln).
From this you can see that if any input list is of length zero then the result will be of length zero (the empty list).
