How to inherit class from different file?
<p>I have two files:</p>

<blockquote>
  <p>fig.py</p>
</blockquote>

<pre><code>import math
PI=math.pi

class Fig:
    def __init__(self):   
        self.name= " "
</code></pre>

<p>And </p>

<blockquote>
  <p>circle.py</p>
</blockquote>

<pre><code>class Circle(Fig):
    def __init__(self, radius):
        self.name= "Circle"
        self.data= ["Radius: ", radius]
</code></pre>

<p>But I am trying to load them I whenever I try it <em>jupyter-notebook</em> throws the error:</p>

<blockquote>
  <p>NameError: name 'Fig' is not defined</p>
</blockquote>

<p>I have tried using <code>import fig</code> at the beggining of <em>circle.py</em> and it does not work, neither does running both files. They are both in the same directory.</p>
