So apparently when you execute your query the result has at least one column but that column isn't named "snumber". I'm sure there is a way in Python to debug "row" and find out what names it does have. Or maybe execute the query in something like psql and observe e column name there.
That said, by default the name of columns whose values are derived by a single function call should be the name of the function. So "translate", not "snumber" - the latter being consumed by the function. You can as use "as <alias>" to give it a different fixed name and refer to that.
