title: Can't access tuple inside 2d array python
body: <p>I have a 2d array that looks much like this:</p>
  
  <pre><code>[[(0, 0), ('', 0), ('', 0), ('', 0), ('', 0), ('', 0)], [(0, 0), ('', 0), ('', 0), ('', 0), ('', 0), ('', 0)]]
  </code></pre>
  
  <p>I am trying to access the values of a tuple from a given cell like this:</p>
  
  <pre><code>x,y = self.cell_array[col][row]
  </code></pre>
  
  <p>It gives me this error:</p>
  
  <pre><code>TypeError: list indices must be integers, not str
  </code></pre>
  
  <p>What am I doing wrong?</p>
