>>> from itertools import repeat, izip
>>> coords = tuple((i,j,k) for i in xrange(1,5) for j in xrange(1,5) for k in xrange(1,2))
>>> locals().update(("tuple%s" % i, coord) for i, coord  in izip(xrange(1,11), repeat(coords)))
>>> tuple1
((1, 1, 1), (1, 2, 1), (1, 3, 1), (1, 4, 1), (2, 1, 1), (2, 2, 1), (2,
3, 1), (2
, 4, 1), (3, 1, 1), (3, 2, 1), (3, 3, 1), (3, 4, 1), (4, 1, 1), (4, 2,
1), (4, 3
, 1), (4, 4, 1))

Does this help?

But I don't understand why you need this?
