title: How to add raw input values in Python?
body: <p>I'm trying to get 2 raw input values added together. Here's the code:</p>
  
  <pre><code>def number_of_limbs(legs, arms, limbs):
      print "You have %s legs O.o" % legs
      print "You also have %s arms o.O" % arms
      print "You have %r limbs!! O.O" % limbs
  
  legs = int(raw_input("How many legs do you have? "))
  arms = int(raw_input("And how many arms do you have? ")
  limbs = legs + arms
  
  number_of_limbs(legs, arms, limbs)
  </code></pre>
  
  <p>It's supposed to ask how many legs, how many arms, and then add them together. Then tell how
  many limbs in total. I'm in lesson 19 of learn python the hard way so that's why i'm doing the "def" thing at the top. I realize there's easier ways to do the exact same thing but i'm trying to grasp the concept of this particular thing. </p>
  
  <p>When I run it, it says I have 2 arms, 2 legs, and 22 limbs. How do I get it to add legs and arms and not just push the two numbers next to each other? </p>
  
  <p>Now it's just saying</p>
  
  <pre><code> File "ex1.py", line 8
      limb = legs + arms
         ^
  SyntaxError: invalid syntax
  </code></pre>
