title: How do I add multiple items to a List in Python?
body: <p>So I have a code that runs a Craigslist type of site, in theory. This is the code.</p>
  
  <pre><code>#Problem 4
  choice = ()
  while choice != 4:
      print "1. Add an item."
      print "2. Find an item."
      print "3. Print the message board."
      print "4. Quit."
      choice = input("Enter your selection:")
      if choice == 4:
          break
  
  #Add an item
      if choice == 1:
          b = "bike"
          m = "microwave"
          d = "dresser"
          t = "truck"
          c = "chicken"
          itemType = raw_input("Enter the item type-b,m,d,t,c:")
          itemCost = input("Enter the item cost:")
          List = []
          List.extend([itemType])
          List.extend([itemCost])
          print List
  </code></pre>
  
  <p>The user should be able to input the choice of 1 enter their items, press 1 again and enter more items. How do I get the list to save without it overwriting the previous input?</p>
