Subject: 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
>>> 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)

and repeat operators:
print "%s" + " %-5.3f" * 7 % <stuff>
