title: create a raw python file in jupyter notebook
body: <p>I am new to Python. I start learning it with Jupyter notebook. It is very useful to test python code at the same time I can document what I've learned with markdown supported by Jupiter.</p>
  <p>Until I started with module/package I noticed that every file ends with &quot; notebook extension <strong>.ipynb</strong>. I understand that in order for Jupyter to have this good-looking visualization it has to store the file in some kind of format.</p>
  <p>is there any solution to create a raw python file using Jupyter?</p>
  <p>I am ok if I have to install other plugins to accomplish this.</p>
