I would like to know what would be python program to do the following. Ask the user to provide the initial investment amount, the percentage interest rate and the number of years for the investment. Then ask the user whether she want the simple interest rate computed or the compound interest rate computed. Ask the user to enter 'C' for compound and 'S' for simple.  Assume that some users may enter lower case responses while some users may enter something else altogether. Your program should account for all situations. Call the appropriate function from the two written above and display the amount accrued.
