Program 5: Word Frequencies (Concordance)

Use a text editor to create a text file (ex: myPaper.txt) It should contain at least 2 paragraphs with around 200 or more words.
Write a Python program (HW19.py) that

asks the user to provide the name of the text file. Be SURE to check that it exists!
Do NOT hard-code the name of the file! Use the entry provided by the user!
read from the text file
NOTE: (write your program so that it ONLY works if it reads from the file specified by the user).

Your program will produce a dictionary of words with the number of times each occurs. It maps a word to the number of times the word occurs

Key: a word
Value: the number of times the word occurs in the text. The report should be an ALPHABETIZED output table, listing the word and the number of occurrences.

NOTES:

The input sequence can be words, numbers or any other immutable Python object, suitable for adict
Ignore case – apple is the same as Apple is the same as APPLE, etc.
Discard all punctuation and extra white space (newlines, tabs, blanks, etc.).
Put the words into a The first time a word is seen, the frequency is 1. Each time the word is seen again, increment the frequency. NOTE: you are REQUIRED to use the dictionary class for this assignment.
Produce a frequency table. To alphabetize the frequency table, extract just the keys and sort them. This sorted sequence of keys can be used to extract the counts from thedict.
Make sure that your output (the table) is formatted so that the columns are aligned, and so that there are titles for each column.
Be sure to modularize your code, using functions appropriately.
The main function should be clean and easy to read, calling the functions with meaningful names. Pass parameters – do not use global variables.

BONUS +5 pts:

Create a menu-driven front-end to this application.
- First, populate the dictionary from the file
- Next, provide a menu that allows the user to
  - Add words to the dictionary
    after asking the user for the word to add
    Note: the count should increase if the word is already there)
  - Check if a word is already in the dictionary
  - Delete a word from the dictionary after asking the user for the word to delete
  - Print the dictionary entries in table form as described above.
- Allow the user to continue using the menu until they choose the option to quit.
