Most teachers will not go as far as the above response without seeing work from you. Do not expect someone here to write the functions for you from A to Z. We offer help, but do not do your homework.
Having said that, if you post your code with which you have difficulties debugging, teachers here will be glad to help you, both for the syntax and the logic.
Write a Function
You will be given one of the following problems to solve using and writing Python functions.
Given a list of words, return an array which indicates the frequency that each letter occurs. For example, in the list [”apple”, ”bob”], [ ’a’ -> 1, ’b’->2, ’e’->1, ’l’->1, ’o’->, ’p’->2] . The order of the array does not matter and a Frequency class will be provided.
Given a list of words, indicate whether the list constitutes a ”Word Lad- der.” A Word Ladder is a series of words where each succeeding word changes by only one letter. You may not assume that all words will be of the same length, and you may not assume the length of the list.
Given an integer greater than 2, X, return an array populated with all prime numbers up to and including X.
