title: Python can't find .txt-file
body: <p>My code doesn't seem to be able to find a text file I created. The <code>.txt</code> file is in the same folder as the <code>.py-file</code> named <code>trivia.txt</code>. It's from the Python programming for the absolute beginner. I get the following error:</p>
  
  <pre><code>&gt;&gt;&gt; 
  Unable to open the file trivia.txt Ending program
   [Errno 2] No such file or directory: 'trivia.txt'
  Traceback (most recent call last):
