Answer 1

If you are OK using sparse arrays, you could use a dict to store your values. Python's dicts allow you to use tuples as keys, as such, you could assign to and access elements of the "sparse array" (which is really a dict here) like this:

d = {}
d[0,2,7] = 123 # assign 123 to x=0, y=2, z=7
v = d[0,2,7]
