title: Namespacing and classes
body: <p>I'm trying to write some (in my opinion) readable code in Python. I need a module that will contain a number of classes. Theoretically I know everything that is needed to accomplish this: I can simply put class definitions in a single module file.</p>
  
  <p>For readability purposes I want to put every class definition into separate file (they are starting to be quite lengthy!), and all these classes into one directory. Whenever I create new file  although it's contents are visible where I need them, class definition that's inside is scoped with unneeded module.</p>
  
  <p>How should I do it? What is 'Python' way to do that?</p>
