title: How to loop through multiple cells in Jupyter / iPython Notebook
body: <p>I've got a Jupyter Notebook with a couple hundred lines of code in it, spread across about 30 cells.  If I want to loop through 10 cells in the middle (e.g. using a For Loop), how do you do that?  Is it even possible, or do you need to merge all the code in your loop into one cell?  </p>
