Question

Using PYTHON create a program to allow the user to enter a phrase or read a file.

Make your program menu-driven to allow the user to select a option to count the total words in the phrase or file. In addition, provide a menu-selection to count the number of words start with a vowel and a selection to count the number of words that start with a consonant.

Include exception handlers for file not found, divide by zero, and index error. Include a generic exception handler to all you to capture any exceptions not handled by the try-except block.
