title: Is there a standardized method to swap two variables in Python?
body: <p>In Python, I've seen two variable values swapped using this syntax:</p>
  
  <pre><code>left, right = right, left
  </code></pre>
  
  <p>Is this considered the standard way to swap two variable values or is there some other means by which two variables are by convention most usually swapped?</p>
