write a function that takes a list as a parameter, converts every element in the list to integar and then prints a tuple comprising of these integar elements. if the function encounters a character such as 'p' that cannot be converted to an integar, it throws this error message on the screen: "error. please enter only integers." example: input: enter elements of list separated by commas: 1,2,3,5 output: (1, 2, 3, 5) input: 1,2,d,5 output: error. please enter only integers.
