title: Python remove elements from two dimensional list
body: <p>Trying to remove min and max values from two dimensional list in array.
  My code:</p>
  
  <pre><code>myList = [[1, 3, 4], [2, 4, 4], [3, 4, 5]]
  maxV = 0
  minV = myList[0]0]
  for list in myList:
     for innerlist in list:
        if innerlist &gt; maxV:
           maxV = innerlist
        if innerlist &lt; minV:
           minV = innerlist
     innerlist.remove(maxV)
     innerlist.remove(minV)
  print(myList)
  </code></pre>
  
  <p>This causes me some erros, which i not particulary understand. I'm quite sure that innerlist is not array but ordinary variable. But still i think it should be somehow possible to remove min and max elements from two dimensional list.
  I mean I need to remove in every innerlist in my list highest and lowest values.
  LF help!
  Regards.</p>
