Number of rows into a HDF5

Question

there's a method for have the number of rows of a .hdf5 without load it in ram ?

I'm using Python 3.4 with pydev on Liclipse (WIndows 10)

Thanky you

Answer 1

if you use the h5py library, you can simply run len(dataset) or dataset.len() (which is recommended).
