[Pytables-users] recursive walk question

[Andre' Walker-L. <wal...@gm...>]

Hi All,

Still trying to sort out a recursive walk through an hdf5 file using pytables.

I have an hdf5 file with an unknown depth of groups/nodes.

I am trying to write a little function to walk down the tree (with user input help) until a data file is found.

I am hoping there is some function one can use to query whether you have found simply a group/node or an actual numpy array of data.  So I can do something like

if f.getNode('/',some_path) == "data_array":
    return f.getNode('/',some_path), True
else:
    return f.getNode('/',some_path), False

where I have some function that if the second returned variable is True, will recognize the file as data, where as if it is False, it will query the user for a further path down the tree.


I suppose I could set this up with a try: except: but was hoping there is some built in functionality to handle this.


Thanks,

Andre
