Hello Robert, You’ll need to use one of Python’s string formatting features, which provide functionality for inserting variables into strings. The current state of the art are f-strings, but note that you will have to double all the curly braces in your query string if you use them because f-strings use curly braces to denote variable names.
Here’s a nice article from Real Python about all three ways to format strings in Python, and their various pros and cons. https://realpython.com/python-f-strings/ Marijane White, M.S.L.I.S.

I find the """ """ style of writing the queries in my code very readable but I am not able to introduce a variable in it. For example: sparql.setQuery(""" select distinct ?id ?eurovoc where { ?atto a ocd:aic . ?atto dc:identifier ?id . ?atto ocd:startDate ?datapres . ?atto <http://purl.org/dc/terms/subject><https://urldefense.com/v3/__http:/purl.org/dc/terms/subject*3E__;JQ!!Mi0JBg!bxw1FRIizJnQ0o2yyvMLGOJADoq06M086Tbb4tbYH8JWoNveq21AnC8S-ReoEb8$> ?eurovoc . FILTER(REGEX(?datapres,'2021\\\\d{4}')) } """) in the above query I would like 2021 to be instantiated by a "year" variable I previously set in the code. Any suggestions? Thank you very much and happy 2022 Robert -- http://github.com/RDFLib<https://urldefense.com/v3/__http:/github.com/RDFLib__;!!Mi0JBg!bxw1FRIizJnQ0o2yyvMLGOJADoq06M086Tbb4tbYH8JWoNveq21AnC8ScFdqFBQ$> --- You received this message because you are subscribed to the Google Groups "rdflib-dev" group.
