Practice python skill by creating a series of functions that take text, manipulate it and develop a vector based on matching a given sentence to a pre-defined list of words

• Create a function unpunctuate that takes a string and removes all punctuation, e.g.
• Write a function get_bag_of_words_for_single_document that, given any string (also called document), e.g. "John also likes to watch football games.", returns its bag of words:
• Write a function get_bag_of_words that uses the above function to achieve the following: given a list of strings, it returns the total bag of words for all of the documents.
• Given a bag of words for all of the documents in our data set, write a function turn_words_into_indices take the keys in the bag of words and alphabetize them
• Given a document, write a function vectorize that turns the document into a list (also will be called a vector) the same length as the number of keys of bag of words where for each index of the list will be 1 only if the word at that index in the word list is contained in the document and 0 otherwise.
