printf-style formatting over the format method."?

Thank you. I had in fact Googled for "Python string" and "Python
string variable replacement names" but I didn't get much further than
the fine Python manual which doesn't clearly name the second method. I
suppose that knowing what to Google for is 90% of the way to an
answer!

Oh? Which book is that? I've so far been learning by writing small
applications here and there. I have been meaning to go through Learn
Python The Hard Way for the longest time.
