title: What is the Python equivalent to the C++ namespace?
body: <p>In C++ I would write:</p>
  
  <pre><code>namespace LowerLevel{
  int DoStuff() {}; //
  }
  </code></pre>
  
  <p>And access it via:</p>
  
  <pre><code>LowerLevel::DoStuff()
  </code></pre>
  
  <p>How do I do both in Python?</p>
