How to randomize a list to meet conditions

I would like to generate n randomized versions of a list such that with each randomization the ordering is different from the one before and also each element must have a different position than in the list before. I have generated a list of all possible permutations of the list but I am stuck on how to select the sub-lists that match my conditions. I am thinking maybe a list comprehension could work but not sure how to complete it.

# constraints: n <= 12

lst = ['John', 'William', 'Michael', 'Victor', 'Tom', 'Charley', 'Patrick', 'David']

permutations = list(itertools.permutations(lst))

randomized_lists = [i for i in permutations if <conditions>]

Any ideas how this could be done? Also, is there a better (more efficient) approach to the problem?
