The h5py package is a Pythonic interface to the HDF5 binary data format.
It lets you store huge amounts of numerical data, and easily manipulate that data from NumPy. For example, you can slice into multi-terabyte datasets stored on disk, as if they were real NumPy arrays. Thousands of datasets can be stored in a single file, categorized and tagged however you want.
We have moved to www.h5py.org.
The h5py project has a brand new website!. You can find downloads, documentation and links to our new GitHub source code repository and bug tracking system.
