It depends on where you come from.
Those of us brought up on C or COBOL are used to separating
the presentation from the data. Those brought up with PASCAL
and BASIC are used to iterleaving data with presentation.
One thing - you don't need all the str() calls in your example,
print already calls str() for you. Also comma separators are
better than + signs since the plus operation on strings is
quite expensive - you create a new string for each addition.
