couldn't solve that

Help please!!!!

even.py 
This one should be short and sweet.
Write a function named even_odd that takes a single argument, a number.
return True if the number is even, or False if the number is odd.
You can use % 2 to find out the remainder when dividing a number by 2. Even numbers won't have a remainder....             

def even_odd(num):
  ??????????????
    return True
else:
    return False

% is the 'modulo' operator. a % b gives you the remainder of a / b. For example:

0 / 2 = 0 with a remainder of 0

1 / 2 = 0 with a remainder of 1

2 / 2 = 1 with a remainder of 0

3 / 2 = 1 with a remainder of 1

4 / 2 = 2 with a remainder of 0.

Notice the padding emerging? Even numbers divided by 2 always result in a remainder of 0, while odd numbers always result in a remainder of 1.

So, if you want to find even numbers, you can replace the ???????? in your code like so:

if num % 2 == 0:
    return True
else:
    return False
