Question

def medianeven (L):
    while len(L) > 2:
        L = L[1:(len(L)-1)]
    return average (L)

def medianodd (L):
    while len(L) > 1:
        L = L[1:(len(L)-         


        

Answer 1

The sort() method call you have in the line:

new = L.sort();

doesn't return anything. Thus 'new' holds 'None', which has no length. I believe doing L.sort() will sort the list in place. Don't need to store it in 'new'.
