title: Can you `source` the `ipython profile` (Jupyter) while in a notebook?
body: <p>The iPython profile or Jupyter profile path: <code>~/.ipython/profile_default/startup/startup.ipy</code></p>
  
  <p>I update this quite often.  </p>
  
  <p><strong>Is there a way to <code>source</code> this within a notebook</strong> like when you're in the terminal and <code>source ~/.bash_profile</code> after you make an update?  My current method is to close the kernel and Jupyter session then restart. </p>
