How to take each nth element of the list (disassembly)

by

Also, imagine we have list that we need to disassemble a list and split it into 4 different lists like these:

[1, 5, 9]
[2, 6, 10]
[3, 7, 11]
[4, 8, 12]

Then we should do the following

params = [0.25, 0.5, 0.75, 1]
a_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
step = 4
for i in range(len(params)):
    element = a_list[i::step]
    print(element)

Use the extended slicing syntax a_list[start:stop:step] to get a new list containing every nth element.
