function name: cap_at_100 o parameters: a number grade • returns: the grade with a maximum of 100 o behavior: This function normalizes grades. If a student does a lot of extra credit they may have a final grade that is greater than 100, but we need to bring that down to 100 for the final grade. If the grade is <= 100 we don't need to change anything. ex: cap_at_100(75) returns 75, and cap_at_100(103) returns 100 function name: bound_0_to_100 o parameters:a number grade o returns: the grade with a minimum of 0 and a maximum of 100 o behavior: In addition to exceeding 100, sometimes a grade will be so spectacularly bad that it falls below 0. In that case we want to normalize it to 0 so all grades fall into the range [0, 100]. ex: bound_0_to_100(75) returns 75, bound_0_to_100(103) returns 100, and bound_0_to_100(-5) returns 0 function name: sum_range • parameters: two numbers, a start and a stop o returns: the sum of numbers in the range [start, stop) o behavior: sums the values in the range excluding the stop but including the start. ex: sum_range (3, 7) returns 3+4+5+6, which is 18 function name: pizza_total o parameters: a number num_pizzas and a bool is_delivery • returns: The total for a pizza order o behavior: Each pizza costs $12 and delivery costs $4. If is_delivery is True, you should add a delivery charge to the total. ex: pizza_total(2, True) returns 28 (12*2 +4), and pizza_total(3, False) returns 36 (12 3) function name: is_even o parameters: a number n o returns: True if n is even (n is a multiple of 2), False otherwise o behavior: ex: is_even(4) is True, and is_even(7) is False function name: is_divisble_by o parameters: two numbers, num and a divisor o returns: True if num is divisible by divisor, False otherwise o behavior: Much like is_even, but rather than checking if it is divisible by 2, check if the number is divisible by divisor. ex: is_divisible_by (9,4) is False, and is_divisible_by (9, 3) is True
