The Python genie grants you that wish. You were almost right:
>>> a = 2.000001
>>> b = 123456.789
>>> c = 1234.0001
>>> print (3 * '%12.3f') % (a, b, c)
2.000 123456.789 1234.000
>>> print 3 * '%12.3f' % (a, b, c)
2.000 123456.789 1234.000
>>> print 3 * '%12.3f' % a, b, c
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: not enough arguments for format string
(Note the spaces and parentheses. Python programmers thank you if put
them improving readability a little).
