Hi there!

Up next are your function tasks. I want to quickly mention a few functions that may be useful to you that you may not have seen yet. Specifically these functions will be useful for Task #7 , the last task.

The modulus operator

This % mod operator returns back the remainder after a division. For example 3 divided by 2 and be shown to be 1 remainder 1. Since 2 goes into 3 one time, with a remainder of 1 (2+1=3). You can use the % operator in Python to view the remainder. For example:

3 % 2  

returns 1

17 % 15 

returns 2 (since its the remainder after the division of 17/15)

100 % 10 

returns 0, since 10 goes into 100 evenly.

This is really useful for figuring out if a number is even or not. You just simply check if the number % 2 returns 0. If it does, then its even.

def even_check(num):
    if num % 2 == 0:
        print("Number was even")
    else:
        print("Odd number")

The sum() function

Just like max() and min(), Python also has a built in sum() function that can return the sum() of all the numbers in a list.

sum([1,2,3,4])  will return back 10.
