title: PyQt: Search Item QTableWidget and take it's coordinates?
body: <p>So, I'm using <strong>Python</strong> and <strong>PyQt</strong> and I have created a <code>QTableWidget</code> which I populate with data.</p>
  
  <p>Is there a way to search for a specific value and if the program finds something, can it return the <code>coordinated(index)</code> of the item?</p>
  
  <p><strong>Update:</strong><br>
  Here's the code:</p>
