Opening a SQLite database in readonly mode

[Paul Moore]

The SQLite documentation mentions a flag, SQLITE_OPEN_READONLY, to
open a database read only. I can't find any equivalent documented in
the Python standard library documentation for the sqlite3 module (or,
for that matter, on the pysqlite library's website).

Is it possible to open a sqlite database in readonly mode, in Python?

Thanks,
Paul.
