A better way to protect passwords is to add a "salt" to all user's passwords on a given site. The salt is a secret string that is prepended to each password before hashing.

Complete the function below that combines the salt with the supplied password to strengthen it$.$ Demonstrate that just hashing the correct password is insufficient to guess the password if you do not know the salt as well $($again use $==).$def salted$\_$hash$($password$)$:

salt $=$ "zoology"

return $0$ # replace $0$ with the salted hash

# compute the salted and hashed version of the password "cardinal"

# demonstrate that we cannot guess without the salt.
