Instructions

In this exercise you are helping your younger sister edit her paper for school. The teacher is looking for correct punctuation, grammar, and excellent word choice.

You have four tasks to clean up and modify strings.

1. Capitalize the title of the paper

Any good paper needs a properly formatted title. Implement the function capitalize_title(<title>) which takes a title str as a parameter and capitalizes the first letter of each word. This function should return a str in title case.

2. Check if each sentence ends with a period

You want to make sure that the punctuation in the paper is perfect. Implement the function check_sentence_ending() that takes sentence as a parameter. This function should return a bool.

3. Clean up spacing

To make the paper look professional, unnecessary spacing needs to be removed. Implement the function clean_up_spacing() that takes sentence as a parameter. The function should remove extra whitespace at both the beginning and the end of the sentence, returning a new, updated sentence str.

4. Replace words with a synonym

To make the paper even better, you can replace some of the adjectives with their synonyms. Write the function replace_word_choice() that takes sentence, old_word, and new_word as parameters. This function should replace all instances of the old_word with the new_word, and return a new str with the updated sentence.
