I recently discovered the maps data structure but it seems I can't dynamically assign new keys to it. I am going through some files and don't know the keys beforehand (unless I loops through everything first to get the keys and then again to get the data). Is it possible to not have to loop through things twice and just instead add new keys as I discover them?

[note this is easy to do in python with a dictionary with `dictionary[new_key] = data` ]

Adding a new key-value pair is same as python e.g map_variable(new_key)= data.

That should work if you do it as is shown by the last example on the containers.Map documentation page. Can you show the full error message (everything in red) you receive when you try? That may show us why it's not working or suggest a further avenue for investigation.
