Tried to make it readable:

def iter_coords(i):
    for j in xrange(1,5):
        for k in xrange(1,2):
            yield i, j, k

def iter_vars():
    for i in xrange(1, 5):
        yield "tuple_%s" % i, tuple(iter_coords(i))

locals().update(dict(iter_vars()))

>>> tuple_1
((1, 1, 1), (1, 2, 1), (1, 3, 1), (1, 4, 1))
>>> tuple_2
((2, 1, 1), (2, 2, 1), (2, 3, 1), (2, 4, 1))
>>> tuple_3
((3, 1, 1), (3, 2, 1), (3, 3, 1), (3, 4, 1))
>>> tuple_4
((4, 1, 1), (4, 2, 1), (4, 3, 1), (4, 4, 1))
