title: How to count by twos with Python's 'range'
body: <p>So imagine I want to go over a loop from 0 to 100, but skipping the odd numbers (so going "two by two").</p>
  
  <pre><code>for x in range(0,100):
      if x%2 == 0:
          print x
  </code></pre>
  
  <p>This fixes it. But imagine I want to do so jumping two numbers? And what about three? Isn't there a way?</p>
