title: Python importing modules that all import another module that is the same
body: <p>What i want to is, I have foo.py it imports classes from bar1, bar2, and they both need bar3, e.g.</p>
  
  <p>foo.py</p>
  
  <pre><code>from src import *
  ...
  </code></pre>
  
  <p>src/ __ init__.py</p>
  
  <pre><code>from bar1 import specialSandwichMaker
  from bar2 import specialMuffinMaker
  </code></pre>
  
  <p>src/bar1.py</p>
  
  <pre><code>import bar3
  class specialSandwichMaker(bar3.sandwichMaker)
  ...
  </code></pre>
  
  <p>src/bar2.py</p>
  
  <pre><code>import bar3
  class specialMuffinMaker(bar3.muffinMaker)
  ...
  </code></pre>
  
  <p>is there a more efficient way to make bar3 available to the bar1 and bar2 files without having them directly import it?</p>
