Yes, but most likely not with pysqlite. The python sqlite3 module in the
standard library, and the pysqlite module are both DB-API compliant, which
means they probably do not have a method to open the DB read only (as that
is usually enforced at the user permission level).
If you want to use that flag, take a look at APSW. It is a very thin layer
on top of the SQLite C API, and thus supports everything that the C API
supports. It is not, however, DB API compliant, but is very close so not
hard to pick up.
BTW, APSW is written by the same author as pysqlite.
