+Module functions
+^^^^^^^^^^^^^^^^
 
-.. data:: apilevel
-
-   String constant stating the supported DB-API level. Required by the DB-API.
-   Hard-coded to ``"2.0"``.
-
-.. data:: paramstyle
-
-   String constant stating the type of parameter marker formatting expected by
-   the :mod:`!sqlite3` module. Required by the DB-API. Hard-coded to
-   ``"qmark"``.
-
-   .. note::
-
-      The :mod:`!sqlite3` module supports both ``qmark`` and ``numeric`` DB-API
-      parameter styles, because that is what the underlying SQLite library
-      supports. However, the DB-API does not allow multiple values for
-      the ``paramstyle`` attribute.
-
-.. data:: version
-
-   Version number of this module as a :class:`string <str>`.
-   This is not the version of the SQLite library.
-
-   .. deprecated-removed:: 3.12 3.14
-      This constant used to reflect the version number of the ``pysqlite``
-      package, a third-party library which used to upstream changes to
-      :mod:`!sqlite3`. Today, it carries no meaning or practical value.
-
-
-.. data:: version_info
-
-   Version number of this module as a :class:`tuple` of :class:`integers <int>`.
-   This is not the version of the SQLite library.

-
-.. data:: sqlite_version_info
-
-   Version number of the runtime SQLite library as a :class:`tuple` of
-   :class:`integers <int>`.
-
-
-.. data:: threadsafety
-
-   Integer constant required by the DB-API 2.0, stating the level of thread
-   safety the :mod:`!sqlite3` module supports. This attribute is set based on
-   the default `threading mode <https://sqlite.org/threadsafe.html>`_ the
-   underlying SQLite library is compiled with. The SQLite threading modes are:
-
-     1. **Single-thread**: In this mode, all mutexes are disabled and SQLite is
-        unsafe to use in more than a single thread at once.
-     2. **Multi-thread**: In this mode, SQLite can be safely used by multiple
-        threads provided that no single database connection is used
-        simultaneously in two or more threads.
-     3. **Serialized**: In serialized mode, SQLite can be safely used by
-        multiple threads with no restriction.
-
-   The mappings from SQLite threading modes to DB-API 2.0 threadsafety levels
-   are as follows:
-
-   +------------------+-----------------+----------------------+-------------------------------+
-   | SQLite threading | `threadsafety`_ | `SQLITE_THREADSAFE`_ | DB-API 2.0 meaning            |

-

-   This flag may be combined with :const:`PARSE_COLNAMES` using the ``|``
-   (bitwise or) operator.

-   Pass this flag value to the *detect_types* parameter of

-   as the converter dictionary key.
-   The type name must be wrapped in square brackets (``[]``).
