You might want to try "new style" string formatting [1], which I think
is better than the "old style" in this particular case:

'Testing 0042'
>>> "Testing {0:0{1}d}".format(42, 9)
'Testing 000000042'
One cannot use a nested field in the 'name' part of the field (before
the ':' (I tried), but are pretty free to nest in the actual
specification part after the ':'.
>>> '{0:{1}}'.format(7,'b')
'111'
>>> '{0:{1}}'.format(7,'d')
'7'
