KeyError Iterating on empty HDFStore

[toobaz]

list(pd.HDFStore("non_existing_store.hdf"))

should, I think, return [], instead it yields:

KeyError: 'No object named 0 in the file'

has nothing to do with an empty store, HDFStore is an iterable (e.g. has __getitem__ and __len__ defined), but not __iter__, so this essentially calls .get. I suppose it should just raise a better error message.

you are probably looking for .keys() (though I suppose __iter__ could just call that)

Sorry, I was mislead by HDFStore().root being iterable. I will implement the __iter__ you suggest.
