Hi all,

Finding topk elements is widely used in several fields, but missed in NumPy.
I implement this functionality named asĀ  numpy.topk using core numpy
functions and open a PR:

Any discussion are welcome.

Thanks for the proposal Kang. I think this functionality is indeed a fairly obvious gap in what Numpy offers, and would make sense to add. A detailed comparison with other libraries would be very helpful here. TensorFlow and JAX call this function `top_k`, while PyTorch, Dask and MXNet call it `topk`.

When I saw `topk` I initially parsed it as "to pk", similar to the current `tolist`. I think `top_k` is more explicit and clear.
