Converting UK national grid to latitude longitude Python function from Hannah Fry

I found Hannah Fry's python function useful with a dataset in national grid coordinates. It's not something that could be done easily in a Tableau calculated field as it is an iterative calculation that converges to the solution. Hannah Fry does have a Tableau connection though; she was a keynote speaker in the London Tableau conference on tour a few years ago. That presentation gave some key insights on Tom Cruise's central upper tooth, as well as showing pictures of two clones of Hannah with symmetrical faces, one based on the left side of her face and one based on the right hand side!
