Reading scalar datasets

[Filipe Maia]

Hi,

This is a really silly question but I couldn't find the answer in the
documentation.
I am trying to read a scalar dataset but I don't know know.
For example lets imagine I create it like

file.create_dataset("distance",data=0.65) # in meters
file.create_dataset("name",data="string")

How do I read this back?

print str(file["name"]) and print file["name"] without much success.

Thanks for the help,
Filipe

It looks a little funny but h5py uses the NumPy syntax:

dataset = file["name"]
data = dataset[()]

With older versions of h5py, dataset.value and dataset[...] will also
work, although these are discouraged.
