title: How can I use common code in python?
body: <p>I'm currently maintaining two of my own applications. They both share some common aspects, and as a result, share some code. So far, I've just copied the modules from one project to the other, but now it's becoming a maintenance issue. I'd rather have the common code in one place, outside of both of the projects, which they can both import. Then, any changes to the common code would be reflected in both project.</p>
  
  <p>My question is: how can I do this? Do I create a library out of this code? If so, how do the dependent projects use the library? I think one thing I struggle with here is that the common code isn't really useful to anyone else, or at least, I don't want to make it a supported modules that other people can use.</p>
  
  <p>If my question isn't clear, please let me know.</p>
