Python: get value from row and column from a matrix
<p>I'm learning how to code and I didn't quite understand how a class really works. If I create a matrix for example:</p>

<pre><code>class Matrix(object):

 def __init__(self,i,j,value):
  self.rows = i
  self.cols = j
  self.value = value
</code></pre>

<p>if I have a random matrix and want to select the biggest value in a row, i can write:</p>

<pre><code>for value in row
</code></pre>

<p>and the program will know I mean the value ij in the ith row?</p>
