Hi John,
What you need here is a loop. Have you learned about for loops? Here is
a short example to get you started. Any Python tutorial will tell you more.
In [1]: rows = [ ['row1', 0], ['row2', 55], ['row3', 23] ]
In [2]: for row in rows:
...: print row[0], row[1]
...:
...:
row1 0
row2 55
row3 23
