title: Swap values in a tuple/list inside a list in python?
body: <p>I have a list of tuples like this:</p>
  <pre><code>[('foo','bar'),('foo1','bar1'),('foofoo','barbar')]
  </code></pre>
  <p>What is the fastest way in python (running on a very low cpu/ram machine) to swap values like this...</p>
  <pre><code>[('bar','foo'),('bar1','foo1'),('barbar','foofoo')]
  </code></pre>
  <p>I am currently using:</p>
  <pre><code>for x in mylist:
      self.my_new_list.append(((x[1]),(x[0])))
  </code></pre>
  <p>Is there a better or faster way???</p>
