Here is a functional variant:

>>> d = [1.2 , 31.1, 1.001]
>>> def format(f):
...     return "%-10f" % f
...
>>> print " ".join(map(format, d))
1.200000   31.100000  1.001000

which can be simplified to

>>> print " ".join(map("%-10f".__mod__, d))
1.200000   31.100000  1.001000

if you like. I'm assuming that the trailing space in your approach was
accidental.
