Print the largest odd number entered
This is a solution that doesn't use lists, and only goes through the input once.

maxOdd = None

for _ in range(10):
    num = int (raw_input("enter num: "))
    if num &amp; 1:
        if maxOdd is None or maxOdd &lt; num:
            maxOdd = num

if maxOdd:
    print "The max odd number is", maxOdd        
else:
    print "There were no odd numbers entered"
