When I started this I knew nothing about sqlite or indeed SQL at all so its
been tough going trying to work out how this all works.
So far I have created a database and a table and added columns and rows
filled with data. But I'm having trouble retrieving

Thank you, Pablo. I think that it is OK now; I'm in the process of testing
the method by working within pycrust. I've made the input data into an array

I have a table like this:
