Split list into chunks

OSCC · Python, List · Nov 2, 2020

Chunks a list into smaller lists of a specified size.

  • Use list() and range() to create a list of the desired size.
  • Use map() on the list and fill it with splices of the given list.
  • Finally, return the created list.
from math import ceil

def chunk(lst, size):
  return list(
    map(lambda x: lst[x * size:x * size + size],
      list(range(ceil(len(lst) / size)))))
chunk([1, 2, 3, 4, 5], 2) # [[1, 2], [3, 4], [5]]
