How to find HDF5 file groups/keys within Python?
<p>Lets's say someone gave me a random HDF5 document. I would like to write a function that checks what are the groups/"keys" used. </p>

<p>Take pandas <code>HDFStore()</code>. For many methods which retrieve HDF5 data, one requires to know the key, e.g. <code>pandas.HDFStore.get()</code></p>

<p>What is the most efficient way to check the identity of keys if not a priori known? </p>
