I Need Help with Python

[Gaijin]

This is as simple as it can get...

Code:

#!usr/bin/env python

temp = raw_input("What's the Temperature? ")
water = raw_input("Is the Water salted? ")

if water == "yes" :
    if int(temp) <= -10:
        print "Water freezes"
    else:
        print "No, It's not cold enough!"
