title: How to import your own .py file as a module to another .py file in sublime
body: <p>I have a ex.py file, where i defined several functions.
  Now, I'm trying to import ex.py to another sorter.py file as a module to use those functions.</p>
  <p>So, inside of sorter.py, I have:</p>
  <pre><code>import ex
  function_name()
  </code></pre>
  <p>NameError: name 'function_name' is not defined</p>
  <p>So, I suppose, i don't have ex.py imported to sorter.py</p>
  <p>Both .py files are in the same directory, which is not childdir for python or sublime installation folder.
  I tried to insert the path to ex.py into sys.path, but that didn't help.
  How can i fix that, considering, that I'm using <strong>sublime text editor</strong>?</p>
