astropy.io.misc.hdf5.write_table_hdf5(table, output, path=None, compression=False, append=False, overwrite=False, serialize_meta=False, **create_dataset_kwargs)[source]

Write a Table object to an HDF5 file

This requires h5py to be installed.


Data table that is to be written to file.

outputstr or File or Group

If a string, the filename to write the table to. If an h5py object, either the file or the group object to write the table to.


The path to which to write the table inside the HDF5 file. This should be relative to the input file or group. If not specified, defaults to __astropy_table__.

compressionbool or str or int

Whether to compress the table inside the HDF5 file. If set to True, 'gzip' compression is used. If a string is specified, it should be one of 'gzip', 'szip', or 'lzf'. If an integer is specified (in the range 0-9), 'gzip' compression is used, and the integer denotes the compression level.


Whether to append the table to an existing HDF5 file.


Whether to overwrite any existing file without warning. If append=True and overwrite=True then only the dataset will be replaced; the file/group will not be overwritten.


Additional keyword arguments are passed to h5py.File.create_dataset() or h5py.Group.create_dataset().
