Query about doing fortran-esque repeat formatting

Hello,

Is there a way to do a repeat formatting command like in Fortran? Rather
that doing this:

print "%s %-5.3f %-5.3f %-5.3f %-5.3f %-5.3f %-5.3f %-5.3f" %
(parmName[i], tmp[i][1], tmp[i][2], tmp[i][4], tmp[i][6], tmp[i][7],
tmp[i][8], tmp[i][9])

Something like this:

print "%s 7%-5.3f % (parmName[i], tmp[i][1], tmp[i][2], tmp[i][4],
tmp[i][6], tmp[i][7], tmp[i][8], tmp[i][9])

regards,

Rob

>>> s = '%s ' + ' %-5.4f' * 7
>>> s
'%s %-5.4f %-5.4f %-5.4f %-5.4f %-5.4f %-5.4f %-5.4f'
>>> print s % ('s',1,2,3,4,5,6,7)
s 1.0000 2.0000 3.0000 4.0000 5.0000 6.0000 7.0000

How about:

print ('%s ' + '%-5.4f ' * 7) % ('text',1,2,3,4,5,6,7)

There certainly is. You can use python's string concatenation
and repeat operators:

print "%s" + " %-5.3f" * 7 % <stuff>

data = tuple(parmName[i]) + tuple(tmp[i])

print "%s" + " %-5.3f" * len(tmp[i]) % data

That should do the trick.
