Split List into N Chunks: Python Coding Challenge

Introduction

In Python, we can split a list into smaller lists of equal size using a simple function. This can be useful when we want to process large amounts of data in smaller chunks. In this challenge, you will be asked to write a function that takes a list and an integer n as input and returns a list of n smaller lists, each containing an equal number of elements from the original list.

Split List into N Chunks

Problem

Write a Python function called chunk_into_n(lst, n) that takes a list lst and an integer n as input and returns a list of n smaller lists, each containing an equal number of elements from the original list. If the original list cannot be split evenly into n smaller lists, the final chunk should contain the remaining elements.

To solve this problem, you can follow these steps:

Calculate the size of each chunk by dividing the length of the original list by n and rounding up to the nearest integer using the math.ceil() function.

Create a new list of size n using the list() and range() functions.

Use the map() function to map each element of the new list to a chunk of the original list the length of size.

Return the list of smaller lists.

Your function should have the following signature:

def chunk_into_n(lst: list, n: int) -> list:

Example

assert chunk_into_n([1, 2, 3, 4, 5, 6, 7], 4) == [[1, 2], [3, 4], [5, 6], [7]] assert chunk_into_n([1, 2, 3, 4, 5, 6, 7], 3) == [[1, 2, 3], [4, 5, 6], [7]] assert chunk_into_n([1, 2, 3, 4, 5, 6, 7], 2) == [[1, 2, 3, 4], [5, 6, 7]] assert chunk_into_n([1, 2, 3, 4, 5, 6, 7], 1) == [[1, 2, 3, 4, 5, 6, 7]]
