Iterate through x (5) items in a python list at a time

Question

Let's say I have a list in python [1, 2, 3, 4, 5, 6, 7, 8, 9]

I'm curious what might be considered the most "pythonic" way to iterate over this list 5 items at a time so the results are:

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

Answer 1

You can use list slicing inside a list comprehension:

s = [1, 2, 3, 4, 5, 6, 7, 8, 9]
new_s = [s[i:i+5] for i in range(len(s)-4)]

Output:

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