ObjectStore.Save() requires a key and value.
when using ObjectStore.Read() it requires a key to Read the value. How can I Read all saved values or retrieve all saved keys so that I can use them to Read all saved values?
Any help would be appreciated.
Thanks

Hi Luke,
We can gather all of the ObjectStore keys with
keys = [str(j).split(',')[0][1:] for _, j in enumerate(qb.ObjectStore.GetEnumerator())]See the attached notebook for reference.
Best,

Thanks, I ended up just saving my value as a dictionary and then reading and adding to it. So there only needs to be one key. I'll keep this in mind though as this way will have more uses if I use ObjectStore again.

Hi Luke,
We've also opened a GitHub Issue to add a `.Keys` attribute to the ObjectStore. Subscribe to our progress here.
