[Numpy-discussion] Padding An Array Along A Single Axis

This should be an easy one but I can not come up with a good solution.
Given an ndarray with a shape of (..., X) I wish to zero-pad it to have
a shape of (..., X + K), presumably obtaining a new array in the process.
My best solution this far is to use
np.zeros(curr.shape[:-1] + (curr.shape[-1] + K,))
followed by an assignment. However, this seems needlessly cumbersome.
I looked at np.pad but it does not seem to provide a means of just
padding a single axis easily.
