title: TkInter: understanding unbind function
body: <p>Does TkInter <a href="http://effbot.org/tkinterbook/widget.htm#Tkinter.Widget.unbind-method" rel="noreferrer">unbind</a> function prevents the widget on which it is applied from binding further events to the widget ?</p>
  
  <p><strong>Clarification:</strong></p>
  
  <p>Let's say I bound events to a canvas earlier in a prgram:</p>
  
  <pre><code> canvas.bind("&lt;Button-1&gt;",some_function)
  </code></pre>
  
  <p>Then at a certain point of the program, we no longer need those events:</p>
  
  <pre><code> canvas.unbind("&lt;Button-1&gt;")
  </code></pre>
  
  <p>Can we later do something like this:</p>
  
  <pre><code> canvas.bind("&lt;Button-1&gt;",OTHER_function)
  </code></pre>
