Python row, column, matrix trouble
<p>I'm writing a python program with with a given </p>

<pre><code>matrix = [['A', 'B', 'C'], 
          ['D', 'E', 'F'], 
          ['G', 'H', 'I']]
</code></pre>

<p>I'm trying to write a code so that I can define the coordinates for each value so that if I if my command is get_coordinate('any value in matrix') it will print out the row and column from the matrix. </p>

<p>I'm having difficulty defining the rows and columns to get this code to work. What I'm really looking for is how can I write row = row of matrix, and column = column of matrix.</p>
