If sqlite3.Row is not dict-like enough to use it directly
self.data = row
you can either convert the Row object with
self.data = dict(row)
or use the recipe for a row factory provided in the documentation at
https://docs.python.org/dev/library/sqlite3.html#sqlite3.Connection.row_factory
that constructs a dict directly.
And now an unsolicited remark: if you have more than one instance of Unknown
you might read the data outside the initialiser or at least keep the
connection open and pass a connection or cursor object to the initialiser.
