Python: how to find value in list smaller than target

Question

For example I have a non-ordered list of values [10, 20, 50, 200, 100, 300, 250, 150]

I have this code which returns the next greater value:

def GetN         


        

Answer 1

a=[4,3,8,2,5]
temp=4
def getSmaller(temp,alist):
    alist.sort()
    for i in range(len(alist)):
        if(i>0 and alist[i]==temp):
            print alist[i-1]
        elif(i==0 and alist[i]==temp):
            print alist[i]
getSmaller(temp,a)
