Is it allowed to use the external data via geocoding library?

Hi everybody,

As written in the official rules it’s not allowed to use any external data or additional data or data sources, which are not not provided on these competition pages. I am not sure if I get this right, therefore I am wondering if I could use the geocoding library written in Python to get the missing latitude and longitude values via the provided geographic location (lga)?

Thank you in anticipation.

Kind regards,
