Wie kann ich ValueError beheben: Parameter sind in SQLite nicht unterstützt? ⇐ Python

[Anonymous]

Ich habe ValueError in SQL. Ich habe einen Einfügenbefehl zum Einfügen von Score in die Datenbank, aber er ändert sich nicht: Es ist immer null. Tatsächlich hashedscore = self.score < /code>, aber der Befehl iM.execute < /code> funktioniert nicht. /> (?) ", (HashedScore)) ValueError: Parameter sind nicht unterstütztes Typ < /p>
