don't use the loop, average should be computed ONCE.

def average(l):
    return sum(l) / len(l)

and median can be computed like this:

def median(l):
    half = len(l) // 2
    if (len(l)%2)==1:
        return l[half]
    else:
        return sum(l[half-1:half+1])/2.0

print "The mean of this list is", average(l_input)
print "The median of this list is", median(l_input)
