title: Importing an own python file, Class not defined
body: <p>I have created the following Classses in a file called my_class.py:</p>
  
  <pre><code>#!/usr/bin/env python
  class MyClassA:
      def __init__(self):
          pass  # do something
  
  class MyClassB:
      def __init__(self):
          pass  # do something
  </code></pre>
  
  <p>When I import that module I get this:</p>
  
  <pre><code>&gt;&gt;&gt; import my_class
  &gt;&gt;&gt; a = MyClassA()
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  NameError: name 'MyClassA' is not defined
  </code></pre>
  
  <p>If I do:</p>
  
  <pre><code>from my_class import MyClassA
  </code></pre>
  
  <p>it works... is there a way I can import all the classes (modules) within that file if there were more and without using the "from X import Y" statement?</p>
