I am trying to convert a list that only contains integers into a nested list. The number of elements in each sub-list within the nested list should be a minimum of one.

Input

input_list = [15281, 15285, 15289, 15282, 15286, 15290, 15283, 15287, 15284, 15288, 14590, 14591, 14592]

Expected output

output_list = [[15281, 15285, 15289], [15282, 15286, 15290], [15283, 15287, 15284], [15288, 14590, 14591], [14592] ]

Is there a way to achieve this without converting all integers in the input list to strings before building the nested list?

Try this : `[input_list[i:i+3] for i in range(0, len(input_list), 3)]` – I'mahdi Jul 25 '22 at 14:18
Why would the integers need to be converted to strings? – sj95126 Jul 25 '22 at 14:19
@sj95126 they were probably going to concatenate everything, take every 15, then change each of those into groups of 5 – Bob th Jul 25 '22 at 14:23
