title: Get max value from a list with lists?
body: <p>So I have a list that contains several list which all have three strings first, then one float number, like: </p>
  
  <pre><code>resultlist = [["1", "1", "a", 8.3931], ["1", "2", "b", 6.3231], ["2", "1", "c", 9.1931]]
  </code></pre>
  
  <p>How do I make a function that returns the maximum value (which here would be 9.1931)? I tried </p>
  
  <pre><code>def MaxValue():
      max_value = max(resultlist)
      return max_value
  </code></pre>
  
  <p>but that just gives me a list.</p>
  
  <p>EDIT: Also, any way I could get the index for where the value comes from? Like, from which sublist?</p>
