title: How to get indexes of elements in a table using python?
body: <p>I think the question is pretty straightforward and needs no further explanation. Basically, if I have a table, how can I get the row and column number based on the element. For example:</p>
  
  <pre><code>0 | 1 | 2
  -----------
  1 | a | b
  -----------
  2 | c | d
  </code></pre>
  
  <p>How could I input b and get 1, 2?</p>
