title: How to swap values in python?
body: <p>I know how to swap two variables together but I want to know if there is a quicker way to follow a certain pattern.</p>
  
  <p>So I have this list of number. <code>list=[1,2,3,4,5,6]</code>
  And what I want to do is to swap a number with the following one and swap the next number with the number after it.                                                                                                 so after swapping them it would become <code>list=[2,1,4,3,6,3]</code> 
  So I was wondering if there was a way to be able to swap the numbers more simply. Thank you.</p>
