"print" implicitely converts an object to a string.
As there are a huge number of potential object types, "print" itself
cannot know all the relevant details regarding string convertion for
all types -- each individual type must help (by defining
"__str__" and/or "__repr__"). If it does not help, you
get a printout as the above.

In an interactive Python session, you can use "help(...)" on
one of those "HDF5 object reference"s. This will show you the
API of the object - i.e. how to interact with the object
(such as accessing/modifying the contained information).
"vars(...)" may also help (it shows the object's (instance) attributes).
