title: How do I merge a value and a range or list in python in a single line?
body: <p>I am quite new to python, and still learning simple data handling in python.
  I would like to combine 1 and range(3) to get a list <code>[1,0,1,2]</code>. What is best way to do this? 
  Is there any easy way like <code>[1,0:3]</code>?</p>
