Problem Statement: This program separates the letters and digits from a string containing both. For example, the string 'a1pha8' contains the letters 'apha' and the digits '18'.
Lab Scenario: The program repeats until the character 'n' is provided as input. The program takes a user input of a string containing both letters and digits. It extracts and separates the letters and digits from the string, adds them to two lists, and displays them.
Consider the following important points:
1) You need to design a user-defined function named extract_letters_and_digits which takes user string as a parameter and returns two lists. One is the list of letters and the other being the list of digits.
a. Hint: Iterate over each character in the user string, check if the character is a letter or a digit. Define two lists and store the letters and digits separately in different lists. You may make use of the isdigit() method as needed.
b. You also need to find a simple docstring for this function.
2) Your program must have a main() function. Function main() designs user menu, should take user input, call the extract_letters_and_digits function, and then prints the lists returned by the function. You need to consider using a 'for' loop for printing both the lists to get full points.
a. No need to find a docstring for the main function
b. Consider a 'while' loop to take user string as long as the user does not provide the character 'n' as the input.
