430 points Exception Error Question. You are going to write an interactive calculator. User input is assumed to be a formula consisting of a number, an operator (+, -, *, /), and another number separated by white space (e.g. 2 * 3). You need to split user input using str.split() and check whether the resulting list is valid (if you are not familiar with the ["Hello" one two "1). For your program: Create a prompt and wait for the user to enter the input formula. Write a parse_input(user_input) function to validate (try...except) all the required input parameters are acceptable. Hint: use input_list = user_input.split() to get the calculator parameters. If the input does not consist of 3 elements, raise a MissingElementError, which is a custom Exception. If the input operator is not one of the five operators, raise a FormulaError, which is a custom Exception. Convert the first and third input to a float (float_value = float(str_value)). Catch any ValueError in not a number and raise a ValueError exception. If the input is valid, perform the calculation and print out the result.
