13.2. Group

class Group(shape=(), dtype=<type 'float'>, model=None, fill=0.0, base=None)

A group object represents a multidimensional, homogeneous group of contiguous numpy arrays. An associated data-type object describes the format of each element in the group (its byte-order, how many bytes it occupies in memory, whether it is an integer or a floating point number, etc.).

A group is very similar to a numpy record array and those not familiar should have a look at numpy first.
