title: Get an Integer from Entry
body: <p>How do I get an integer type from the Tkinter <code>Entry</code> widget?</p>
  
  <p>If I try to get the value using <code>variable_name.get()</code>, it says it is a <code>str</code>. If I try to change the type using <code>int(variable_name.get())</code>, it says int can only accept a string or number.</p>
  
  <p>Any help would be welcome!</p>
