```I'm trying to understand what you want to do, but I'm afraid it's still not
clear, so I'm sorry if that reply doesn't help either.

It looks to me as if you first want to convert your list of lists into a
list of arrays, then iterate through this list of arrays.
If that's it, then you can just do:

def p(option_lists):
list_of_arrays = map(numpy.array, option_lists)
for my_array in list_of_arrays:
... # Do some operation on array 'my_array'
