information about a database connection specification.
The URL object is created automatically when
:func:`~sqlalchemy.engine.create_engine` is called with a string
argument; alternatively, the URL is a public-facing construct which can
be used directly and is also accepted directly by ``create_engine()``.

Represent the components of a URL used to connect to a database.
URLs are typically constructed from a fully formatted URL string, where the
:func:`.make_url` function is used internally by the
:func:`_sa.create_engine` function in order to parse the URL string into
its individual components, which are then used to construct a new
:class:`.URL` object. When parsing from a formatted URL string, the parsing
format generally follows
`RFC-1738 <https://www.ietf.org/rfc/rfc1738.txt>`_, with some exceptions.
A :class:`_engine.URL` object may also be produced directly, either by
using the :func:`.make_url` function with a fully formed URL string, or
by using the :meth:`_engine.URL.create` constructor in order
to construct a :class:`_engine.URL` programmatically given individual
fields. The resulting :class:`.URL` object may be passed directly to
:func:`_sa.create_engine` in place of a string argument, which will bypass
the usage of :func:`.make_url` within the engine's creation process.
.. versionchanged:: 1.4
The :class:`_engine.URL` object is now an immutable object. To
create a URL, use the :func:`_engine.make_url` or
:meth:`_engine.URL.create` function / method. To modify
a :class:`_engine.URL`, use methods like
:meth:`_engine.URL.set` and
:meth:`_engine.URL.update_query_dict` to return a new
:class:`_engine.URL` object with modifications. See notes for this
change at :ref:`change_5526`.
.. seealso::
:ref:`database_urls`
:class:`_engine.URL` contains the following attributes:
* :attr:`_engine.URL.drivername`: database backend and driver name, such as
``postgresql+psycopg2``
* :attr:`_engine.URL.username`: username string
* :attr:`_engine.URL.password`: password string
* :attr:`_engine.URL.host`: string hostname
* :attr:`_engine.URL.port`: integer port number
* :attr:`_engine.URL.database`: string database name
* :attr:`_engine.URL.query`: an immutable mapping representing the query
string. contains strings for keys and either strings or tuples of
strings for values.

:ref:`database_urls`
:param drivername: the name of the database backend. This name will
correspond to a module in sqlalchemy/databases or a third party
plug-in.
:param username: The user name.
:param password: database password. Is typically a string, but may
also be an object that can be stringified with ``str()``.
.. note:: The password string should **not** be URL encoded when
passed as an argument to :meth:`_engine.URL.create`; the string
should contain the password characters exactly as they would be
typed.
.. note:: A password-producing object will be stringified only
**once** per :class:`_engine.Engine` object. For dynamic password
generation per connect, see :ref:`engines_dynamic_tokens`.
:param host: The name of the host.
:param port: The port number.
:param database: The database name.
:param query: A dictionary of string keys to string values to be passed
to the dialect and/or the DBAPI upon connect. To specify non-string
parameters to a Python DBAPI directly, use the
:paramref:`_sa.create_engine.connect_args` parameter to
:func:`_sa.create_engine`. See also
:attr:`_engine.URL.normalized_query` for a dictionary that is
consistently string->list of string.
:return: new :class:`_engine.URL` object.
.. versionadded:: 1.4
The :class:`_engine.URL` object is now an **immutable named
tuple**. In addition, the ``query`` dictionary is also immutable.
To create a URL, use the :func:`_engine.url.make_url` or
:meth:`_engine.URL.create` function/ method. To modify a
:class:`_engine.URL`, use the :meth:`_engine.URL.set` and
:meth:`_engine.URL.update_query` methods.

As the :attr:`_engine.URL.query` dictionary may contain either
string values or sequences of string values to differentiate between
parameters that are specified multiple times in the query string,
code that needs to handle multiple parameters generically will wish
to use this attribute so that all parameters present are presented
as sequences. Inspiration is from Python's ``urllib.parse.parse_qs``
function. E.g.::
