One way to do it:

>>> def adjust(f, width, dec):
...     pos = f.find(".")
...     if pos == -1:
...             pos = len(f)
...     dec += 1
...     return "%*s%-*s" % (width-dec, f[:pos], dec, f[pos:])
...
>>> print "\n".join([repr(adjust("%s" % f, 10, 5)) for f in [1, 2.3456,
42.42]])
'   1      '
'   2.3456 '
'  42.42   '
