I want to create a script that returns the day of the week,`s` is a string that represents the day of the week, and
`k` is an int that returns the day of the week that is K days later. 

This is my code:

```
weekday = {
    "Mon": 0,
    "Tue": 1,
    "Wed": 2,
    "Thu": 3,
    "Fri": 4,
    "Sat": 5,
    "Sun": 6
}

def wd(s, k):
    s = list(weekday.values())[list(weekday.keys()).index(s)]
    k %= 7
    result = s + k
    return result

print(wd('Sat', 23))

```
