Oh well since a few solutions have already been posted I thought I
might add another, just so you at the very least you have to do some
work making up your mind which one to choose. Using an incremental
approach just to be different ...

Really?

Anything?! Sorry to be persnickety here, but what about this:
class C :
def __int__ (self) : pass
'%d' % C()
or this:
def foo (val) : return val
foo
In practice the different placeholders give you a handle to achieve
different formatting effects.
Compare for example:
for x in range(15) :
print '%02d' % x
against:
for x in range(15) :
print '%02s' % x
#the '0' in this case being redundant
Or again:
from math import pi
print '%.4f' %

Isn't a regexp overkill here when this will do:

The difference is simply that an empty line contains a '\n' while EOF
does not. If you strip() your line before testing you will have
trouble. But the minimal cases you post (p
