Chunk a List Into Fixed Sizes

EasyPython15 min10 XP

Problem

Given a list and positive chunk size k, return a list of chunks. The final chunk may be smaller.

Why This Matters

Chunking appears in batching API calls, processing datasets, and preparing mini-batches for training.

Function Signature

def chunk_list(items, k):

Examples

Example 1

Input[1, 2, 3, 4, 5], k = 2

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

The leftover value 5 still becomes a final chunk.

Constraints

Return the exact requested structure.
Handle normal edge cases cleanly.
Prefer readable code over clever shortcuts.

CodePython

def chunk_list(items, k):
    """
    Input example: [1, 2, 3, 4, 5], k = 2
    Return: [[1, 2], [3, 4], [5]]
    Return the value from the function so the tests can compare it. Do not print unless the prompt asks.
    """
    # write your code here
    return []

def chunk_list(items, k):
    """
    Input example: [1, 2, 3, 4, 5], k = 2
    Return: [[1, 2], [3, 4], [5]]
    Return the value from the function so the tests can compare it. Do not print unless the prompt asks.

Core example

Input[1, 2, 3, 4, 5], k = 2

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

The leftover value 5 still becomes a final chunk.
