A> What you may not realize is that a leading zero means "octal" in python.

Only in an integer constant in a piece of Python source code. How it is
interpreted in any other context is up te the software (or person) that
interprets it. So printing "010" in some output in no way forces it to be
interpreted as octal.

So how is that different from print "%03d" % 10? And moreover the str is
superfluous as "0%s" % 10 already yields a string. And the %s doesn't do
much different from %d in this case. Certainly not anything that has to do
with decimal or octal.
