title: ImportError: attempted relative import with no known parent package
body: <p>Can't seem to find a straightforward answer to this question.  All I want to know is how to import the file I saved under my <code>\scripts</code> directory.</p>
  
  <p>I added the path to <code>sys.path</code>...</p>
  
  <pre><code>import sys
  sys.path.insert(0, "C:\\my_Stuff\\data_science\\scripts")
  </code></pre>
  
  <p>I added a <code>__init__.py</code> file under my <code>\scripts</code> directory, which is the same directory where my <code>tree.py</code> file is.  </p>
  
  <p>I run...</p>
  
  <pre><code>import tree as tr
  </code></pre>
  
  <p>...but am still getting the error.</p>
