title: In Python how to recover from joke statements like True = False
body: <p>I started learning Python just today using Python 2.7 and I have a question here about global variables True and False:</p>
  
  <p>It seems I can overwrite the value of True and False as this:</p>
  
  <pre><code>False = True
  # now the value of variable False is also true.
  True = False
  # because the value of False is true, after this the value of True is still true.
  
  if True(or False):
      print 'xxxx'
  else:
      print 'yyyy'
  </code></pre>
  
  <p>Now wether we put True or we put False as the if condition, it always prints 'xxxx'.</p>
  
  <p>Then how to recover from that fault situation? I imagine that we could use something like:</p>
  
  <pre><code>True = 1==1
  False = 1!=1
  </code></pre>
  
  <p>but that seems bit dodgy to me. Is there any better way to do that?</p>
  
  <p>Thanks.</p>
  
  <p>(Also, it seems in Python 3.3 this action is no longer allowed?)</p>
