title: How to include external Python code to use in other files?
body: <p>If you have a collection of methods in a file, is there a way to include those files in another file, but call them without any prefix (i.e. file prefix)?</p>
  
  <p>So if I have:</p>
  
  <pre><code>[Math.py]
  def Calculate ( num )
  </code></pre>
  
  <p>How do I call it like this:</p>
  
  <pre><code>[Tool.py]
  using Math.py
  
  for i in range ( 5 ) :
      Calculate ( i )
  </code></pre>
