title: How to test that variable is not equal to multiple things?
body: <p>This is the piece of code I have:</p>
  
  <pre><code>choice = ""
  
  while choice != "1" and choice != "2" and choice != "3": 
      choice = raw_input("pick 1, 2 or 3")
  
      if choice == "1":
          print "1 it is!"
  
      elif choice == "2":
          print "2 it is!"
  
      elif choice == "3":
          print "3 it is!"
  
      else:
          print "You should choose 1, 2 or 3"
  </code></pre>
  
  <p>While it works, I feel that it's really clumsy, specifically the while clause. What if I have more acceptable choices? Is there a better way to make the clause? </p>
