Part A Create a program called ph.py that determines the acidity or basicity of a solution. It should ask the user to enter a numeric pH value. It should then call a function that accepts the value as a parameter and returns a string indicating that the solution is acidic (pH less than 7), basic (pH greater than 7), or neutral (pH is 7); it should return "invalid" if the value is greater than 14 or less than zero*. Finally, your script should then output the returned string for the user to see. *Note that values less than 0 or greater than 14 are okay in reality--but for this assignment we'll consider them invalid. Part B Create a program called price.py that calculates the price of a purchase, including tax. Use a prompt to get (from the user) the subtotal of a purchase and the tax rate percentage. Then call a user-defined function that accepts both values as parameters and returns a total price. Display this returned value for the user.
