Python: Tips of the Day

Chunks a list into smaller lists of a specified size:

Example:

from math import ceil

def tips_chunk(lst, size):
  return list(
    map(lambda x: lst[x * size:x * size + size],
      list(range(0, ceil(len(lst) / size)))))

print(tips_chunk([1, 2, 3, 4, 5, 6], 3))

Output:

[[1, 2, 3], [4, 5, 6]]
