+Chunks a list into  `n`  smaller lists.
+ 
+-   Use  `math.ceil()`  and  `len()`  to get the size of each chunk.
+-   Use  `list()` and `range()`  to create a new list of size  `n`.
+-   Use  `map()`  to map each element of the new list to a chunk the length of  `size`.
+-   If the original list can't be split evenly, the final chunk will contain the remaining elements.

+from math import ceil
+
+def chunk_into_n(lst, n):
+  size = ceil(len(lst) / n)
+  return list(
+    map(lambda x: lst[x * size:x * size + size],
+    list(range(0, n)))
+  )

+chunk_into_n([1, 2, 3, 4, 5, 6, 7], 4)) # [[1, 2], [3, 4], [5, 6], [7]]

-Splits a long list into "`parts`" number of smaller lists, which are as close as possible to each other in length.
-
-- Check if `parts` is larger than `len(lst)` in order to not split the list into more parts than there are elements.
-- The `max(len(lst), 1)` check will handle zero length lists, but `parts < 1` will yield bad results.
-- `k = len(lst)//n` -> an integer specifying the number of elements in each shorter list (i.e. the quotient).
-- `m = len(lst)%n` -> if `len(lst)/n` does not equal a whole number, this equals how many "extra" elements there are (i.e. the remainder).
-- In order to get `n` short lists, every loop iteration goes to `i * k` and then take the next `k` elements.
-- If `m > 0`, then the early iterations will have one extra element in their list until `i > m` (no extra elements left).
-- Return a meta-list containing all these shorter lists.
