In this case yes but the point I was trying to illustrate
was that you often want to print the same message from
several different places in your code - even in different
functions for example. Using a format string helps keep
that consistent. The if/else construct was just the most
concise example I could think of.

Indeed, and I did point that out at the start of my message.
Apart from one string addition the OPs use of print was
pretty seamless. But he wanted to know why the other
programmer thought formatting was better, not whether we thought
formatting was better in his particular case. At least that's
how I read it.
