Python: Chunk a given list into smaller lists of a specified size

Python List: Exercise - 232 with Solution

Write a Python program to chunk a given 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.

Sample Solution:

Python Code:

from math import ceil
def chunk_list(lst, size):
  return list(
    map(lambda x: lst[x * size:x * size + size],
      list(range(ceil(len(lst) / size)))))
print(chunk_list([1, 2, 3, 4, 5, 6, 7, 8], 3))

Sample Output: 

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

Python: Tips of the Day

Returns True if the provided function returns True for every element in the list, False otherwise:

Example:

def tips_every(lst, fn=lambda x: x):
  return all(map(fn, lst))

print(tips_every([2, 4, 3], lambda x: x > 1))
print(tips_every([1, 2, 3]))

Output:

True
True
