The h5py package provides both a high- and low-level interface to the
HDF5 library from Python. The low-level interface is intended to be a
complete wrapping of the HDF5 API, while the high-level component
supports access to HDF5 files, data sets and groups using established
Python and NumPy concepts.
A strong emphasis on automatic conversion between Python (Numpy)
data types and data structures and their HDF5 equivalents vastly
simplifies the process of reading and writing data from Python.
