python string format for variable tuple lengths

I have a tuple of numbers let's say nums = (1, 2, 3). The length of nums is not constant. Is there a way of using string formatting in python to do something like this

>>>print '%3d' % nums

that will produce

>>>   1   2   3

Hope it's not a repeat question, but I can't find it if it is. Thanks

Using ''.format

nums = (1, 2, 3)
print(''.join('{:3d} '.format(x) for x in nums))

producing

>>>  1  2  3

params = '%d'
for i in range(1,15):
    try:
        newnum = (params)%nums
    except:
        params = params + ',%d'
        next
    print newnum

Is this enough for you?

print ' '.join(str(x) for x in nums)

Since nobody's said it yet:

''.join('%3d' % num for num in nums)

You could use .join():

nums = (1, 2, 3)
"\t".join(str(x) for x in nums) # Joins each num together with a tab.

Try this:

print ('%3d'*len(nums)) % tuple(nums)
