title: How to switch between loops?
body: <p>I have a program that generates two lists. I want to print an item from list1 then switch to printing an item from list 2 and then go back to printing from list1 ..etc. However whenever I try it it just prints list1 then list2. </p>
  
  <p>Please help.</p>
  
  <p><strong>Code:</strong></p>
  
  <pre><code>List1 = ['a', 'b' , 'c', 'd', 'e', 'f']
  
  List2 = ['1', '2', '3', '4', '5', '6']
  
  continue = True
  
  while continue == True:
      for i in List1:
          print i
          print '/n'
          continue = False
  
  while continue == False:
       for i in List2:
            print i
            print '/n'
            continue = True
