subdtype
¶
Tuple (item_dtype, shape)
if this dtype describes a sub-array, and None otherwise.
The shape is the fixed shape of the sub-array described by this data type, and item_dtype the data type of the array.
If a field whose dtype object has this attribute is retrieved, then the extra dimensions implied by shape are tacked on to the end of the retrieved array.
