title: How to install my own python module (package) via conda and watch its changes
body: <p>I have a file <code>mysql.py</code>, which I use in almost all of my projects. Since I do not want to copy and paste the same file into each of these projects I wrote a module - possibly a package in the future. </p>
  
  <h1>Question</h1>
  
  <p>How do I add a local module to my conda environment, and automatically update or watch it when I change something in <code>mysql.py</code>? How to do the same for a package?</p>
  
  <p>I would like to avoid to set up a local channel/repository and just reference to the folder with <code>mysql.py</code>.</p>
