# $5.$Lists

# Write a function that will take a string of comma$-$separated integers $($assume $\text{'},\text{'}$ between each integer$)$

# and returns a list of those integers in descenging order

def sort$\_$string$($text$)$:

# your implementation here: don't forget to "return" something

# For example, sort$\_$string$(\text{'}1,2,3\text{'})$ should return $[3,2,1]$
