Numpy: how to make parameterized slice?

Question

I have this:

slice = ar[starts[0] : ends[0], starts[1] : ends[1], starts[2] : ends[2]]

How to make something like this:

slice = ar[starts[i] : ends[i] for i in range(3)]

Answer 1

First, don't use slice as a variable name, as it is a builtin.

Second, what you are looking for uses that builtin:

ar[tuple(slice(s, e) for s, e in zip(starts, ends))]
