Python - h5py 2.0

HDF5 for Python (h5py) is a general-purpose Python interface to the Hierarchical Data Format library.
HDF5 is a versatile, mature scientific software library designed for the fast, flexible storage of enormous amounts of data.
A major design goal of h5py is interoperability; you can read your existing data in HDF5 format, and create new files that any HDF5- aware program can understand.
