circular numpy array indices

Question

I have a 1-D numpy array a = [1,2,3,4,5,6] and a function that gets two inputs, starting_index and ending_index, and returns a[stari

Answer 1

This circles forever.

def circular_indices(lb, ub, thresh):
    indices = []
    while True:
        stop = min(ub, thresh)
        ix = np.arange(lb, stop)
        indices.append(ix)
        if stop != ub:
            diff = ub - stop
            lb = 0
            ub = diff
        else:
            break

    return np.concatenate(indices)
