I want to test if the input is a multiple of 4 or not, and if it's not, then simply round UP the input to the nearest multiple of 4 (16, 20, 24, etc depending where the input number is).

Please have a look at the following code:

```
num = input("Enter a number: ")
if num != #a multiple of 4:
     num = round(num) #BUT round it up to the nearest multiple of 4, not just any number

```

any help would be appreciated, thanks!
