Design a Python function named "createSum()" that: (7 marks) -Reads in a string of numbers. - Converts the string to a list of integer numbers. -If the first number is odd, compute the sum of all the numbers. - Otherwise, if the first number is even, compute the product of all the numbers. -Returns the value that you computed above. Include docstring. Ex: if the string is '5 3 6' it would return 14. If the string is '4 2 5' it would return 40.21) You have been asked to write an application for Bakery in Python.
