I would like to have a list of lists N times deep, and my solution is (in
pseudocode):

def deep(x):
  a=[x]
  return a

mylist=[]
for N: mylist=deep(mylist)

Is there a more elegant way to do it?

The maine idea is: from a list having the numbre of steps along N
dimensions, generate a list with an item at each possible point.

Example 1: N=2  list=[2,3]  result=[[1,2],[1,2],[1,2]]
Example 2: N=3  list=[3,1,2]  result=[[[1,2,3]],[[1,2,3]]]
