Hdf5 for python (h5py) is a general-purpose python interface to the hierarchical data format library, version 5. hdf5 is a versatile, mature scientific software library designed for the fast, flexible storage of enormous amounts of data.

from a python programmer's perspective, hdf5 provides a robust way to store data, organized by name in a tree-like fashion. you can create datasets (arrays on disk) hundreds of gigabytes in size, and perform random-access i/o on desired sections. datasets are organized in a filesystem-like hierarchy using containers called "groups", and accessed using the tradional posix /path/to/resource syntax.

h5py provides a simple, robust read/write interface to hdf5 data from python. existing python and numpy concepts are used for the interface; for example, datasets on disk are represented by a proxy class that supports slicing, and has dtype and shape attributes. hdf5 groups are presented using a dictionary metaphor, indexed by name.

this package provides h5py for the python 3 debug interpreter.
