title: Executing Python File from A String Directory in Jupyter Notebook
body: <p>Currently I am running a .py file at Jupyter Notebook using the following command:</p>
  
  <pre><code>!python /Users/manage.py /Users/u.data
  </code></pre>
  
  <p>Sometimes I have a really long file path. Thus, is there a way that I can execute it with anything similar to this?</p>
  
  <pre><code>path_name = "/Users/"
  !python "{}manage.py".format(path_name) "{}u.data.format(path_name)
  </code></pre>
