Can someone please help me with this question? Thank you!

import os datadir - "publicdata" Q1 Write a function lineLengths(filepath) that processes a file, line by fine, and accumulates and returns a list of tuples, one per line. Each tuple consists of the line number and the length of the fine, excluding any leading or trailing whitespace (spaces, tabs, or newlines). Line numbers in a file start at 1. So, for the hello.txt file: Hello, world! Welcome to 'Introduction to Data Systens'. the result is the list of tuples: {(1, 13), (2, 42). In YOUR CODE HERE raise Not ImplementedError() In 1 filepathos path.join(datadir,"hello.txt"> Sanity check print(lineLengths filepath) Run tests assert lineLengths (filepath) - 141, 13), (2, 4211 filepath - 08.path.join(datadir, tennyson.txt") assert lineLengths(filepath) - (1, 26), (2, 24), (3, 0), (4,40), (5, 14)1
