title: Converting tuple to list
body: <p>I am trying to convert this tuple into a list, however when I run this code:</p>
  
  <pre><code>mytuple=('7578',), ('6052',), ('8976',), ('9946',)
  List=[]
  for i in mytuple:
      Start,Mid,End = map(str, mytuple.split("'"))
      List.append(Mid)
  print(List)
  </code></pre>
  
  <p>I receive this error:</p>
  
  <pre><code>AttributeError: 'tuple' object has no attribute 'split'
  </code></pre>
  
  <p>The output should be:</p>
  
  <pre><code>[7578, 6052, 8976, 9946]
  </code></pre>
