Create a file words.txt that contains a paragraph of random words (approximately 100 words long). Next, create a program that prompts for the file name then iterates through each word in this file and counts the frequency of each letter (a through z) and stores the values in a dictionary. Make each letter lowercased and ignore punctuation. Print a histogram of the word counts. You may use "words.txt" included with this assignment. Hints: Python provides a module that stores various groups of characters as a string. If you import the string module, you will see that it contains a number of predefined strings, including: string.punctuation: '!"#$%&\'()*+,-./:; ?@[\\]^_`\{\}" || string.digits: '0123456789' string.ascii.lowercase: 'abcdefghijklmnopqrstuvwxxZ
