Hello Mensanator, thank you for answering in such a short time.

Sorry about that; I have the habit of counting the point as a decimal
place too.

I understood the above from help, but it's not what's been bugging me.
Mea culpa, I've defined the question in a confusing way, I see that
now. What I've meant to ask was, when I have 3 numbers, how would you
print them with the same format which would apply to them 3 numbers.

for example, I have
print a,b,c

now if I print them with 
print '%12.3f' %a,b,c
the format will apply only to a, and not to b and c. I could of course
write
print '%12.3f %12.3f ... 3 times
but that is just unpractical.

Is there a way to just do something like this (not normal syntax, just
my wishful thinking):
print 3*'%12.3f' %a,b,c
(meaning - use this format for the next 3 real numbers that come
along)
