Always get printed value of "None"
<p>Alright so here is my code, I get the result I want but I keep getting the "None" value under it. How do I eliminate the "None" value?</p>

<pre><code>n = input("What day of the week are you leaving?")
r = input("How many days will you be resting?") 

def days(n):
    if n == 0:
        print "Sunday"
    elif n == 1:
        print "Monday"
    elif n == 2:
        print "Tuesday"
    elif n == 3:
        print "Wednesday"
    elif n == 4:
        print "Thrusday"
    elif n == 5:
        print "Friday"
    elif n == 6:
        print "Saturday"
    elif n &gt;= 7:
        print days(n%7)



print days(n+r)
</code></pre>
