How to switch between loops?
<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
</code></pre>

<p><strong>Output:</strong> </p>

<pre><code>a
b
c
d
e
f
1
2
3
4
5
6
</code></pre>

<p><strong>Desired output:</strong></p>

<pre><code>a
1
b
2
c
3
d
4
e
5
f
6
</code></pre>
