Zero-rank arrays are array with shape=(). For example:
>>> x = array(1) >>> x.shape ()
Indexing of Zero-Rank Arrays
As of NumPy release 0.9.3, zero-rank arrays do not support any indexing
>>> x[...] Traceback (most recent call last): File "<stdin>", line 1, in ? IndexError: 0-d arrays can't be indexed.
On the other hand there are several cases that make sense for rank-zero arrays.
