I'd suggest, if this is what you're referring to:

x = seq.split('\n  ')
array_list = [ ]
next_3_d_array = []
range_of_seq = len(seq)
for num in range(0,range_of_seq):
       if num % 3 != 0:
               next_3_d_array.append(num)
       if num % 3 == 0:
                   array_list.append(next_3_d_array)
                   next_3_d_array = [ ]
