title: Tkinter, Label/Text in canvas.rectangle [python]
body: <p>I need to place a text/label centred in a canvas rectangle in tkinter.</p>
  
  <p>First I have a canvas covering the whole screen(800, 600).
  And then I have a couple of rectangles which I made using the:</p>
  
  <pre><code>create_rectangle(...)
  </code></pre>
  
  <p>The first X of the first rectangle is 275 and the second X is 525.</p>
  
  <p>The first Y of the first rectangle is 265 and the second Y is 315.</p>
  
  <pre><code>menuBtn1 = canvas.create_rectangle(275, 165, 525, 215, fill="#C2B6BF")
  </code></pre>
  
  <p>Now how I can place a text/label in the center of this rectangle?</p>
