Python Inheritance Error
<p>I am tring to print self.row with display function. However, the error says There is no no such self.row attribute when it is clearly in the class member.</p>

<p>Please can anyone explain to me what I am doing wrong?</p>

<p>thanks.</p>

<pre><code>from Grid import Grid

class Matrix(Grid):
    def _init__(self, m, n, value=None):
        Grid.__init__(m, n)
        self.row = m
        self.col = n
    def display(self):
        print self.row
</code></pre>
