Split List into Chunks: Efficient Python Coding Challenge

Introduction

In Python, we often need to split a list into smaller lists of a specified size. This can be useful for various purposes, such as processing data in batches or displaying data in a paginated format. In this challenge, you will be tasked with writing a function that can split a list into smaller lists of a specified size.

Split list into chunks

Problem

Write a function chunk(lst, size) that takes a list lst and a positive integer size as arguments and returns a list of smaller lists, each of which has a maximum size of size. If the length of lst is not evenly divisible by size, the last list in the returned list should contain the remaining elements.

Example

chunk([1, 2, 3, 4, 5], 2) ## [[1, 2], [3, 4], [5]] chunk([1, 2, 3, 4, 5], 3) ## [[1, 2, 3], [4, 5]] chunk([1, 2, 3, 4, 5], 1) ## [[1], [2], [3], [4], [5]]

Summary

In this challenge, you have learned how to split a list into smaller lists of a specified size. You have written a function that takes a list and a positive integer as arguments and returns a list of smaller lists, each of which has a maximum size of the given integer. This can be useful for various purposes, such as processing data in batches or displaying data in a paginated format.
