It sounds like you're not calling conn.commit() before you close the
database. By default sqlite (and any other DBAPI 2.0 compliant sql
wrapper) will start in transactional mode. You need to commit() your
transactions or they will be rolled back when you close the database
connection. If you don't want to call commit on your own, you can
switch the database into autocommit mode by setting the isolation
level to None when you open the connection, like this:
conn = sqlite3.connect('.\optiondata', isolation_level=None)
