Question #2 Write a Python user-defined function that accepts a string of any length and first displays the string followed by a horizontal frequency graph of all ALPHABETIC letters only in the string (in alphabetical order). Case of letters, spaces, and all non-alphabetic characters are to be ignored! The function prototype MUST be: def alphaFrequency(userString) For example, the function call: alphaFrequency("This is a Python test 123!") would display: This is a Python test 123! a=1 * e=1 * h=2 ** i=2 ** n=1 * o=1 * p=1 * s=3 *** t=4 **** y=1 * HINT: Consider using Python's upper( ), lower( ), and ord( ) functions and string.ascii_lowercase and string.ascii_uppercase to complete your solution.
