lts to '.+' (match any non-empty
        string). The default value will return all tables contained on a page.
        This value is converted to a regular expression so that there is
        consistent behavior between Beautiful Soup and lxml.

    flavor : str, optional
        The parsing engine to use. 'bs4' and 'html5lib' are synonymous with
        each other, they are both there for backwards compatibility. The
        default of ``None`` tries to use ``lxml`` to parse and if that fails it
        falls back on ``bs4`` + ``html5lib``.

    header : int or list-like, optional
        The row (or list of rows for a :class:`~pandas.MultiIndex`) to use to
        make the columns headers.

    index_col : int or list-like, optional
        The column (or list of columns) to use to create the index.

    skiprows : int, list-like or slice, optional
        Number of rows to skip after parsing the column integer. 0-based. If a
        sequence of integers or a slice is given, will skip the rows indexed by
        that sequence.  Note that a single element sequence means 'skip the nth
        row' whereas an integer means 'skip n rows'.

    attrs : dict, optional
        This is a dictionary of attributes that you can pass to use to identify
        the table in the HTML. These are not checked for validity before being
        passed to lxml or Beautiful Soup. However, these attributes must be
        valid HTML table attributes to work correctly. For example, ::

            attrs = {{'id': 'table'}}

        is a valid attribute dictionary because the 'id' HTML tag attribute is
        a valid HTML attribute for *any* HTML tag as per `this document
        <https://html.spec.whatwg.org/multipage/dom.html#global-attributes>`__. ::

            attrs = {{'asdf': 'table'}}

        is *not* a valid attribute dictionary because 'asdf' is not a valid
        HTML attribute even if it is a valid XML attribute.  Valid HTML 4.01
        table attributes can be found `here
        <http://www.w3.org/TR/REC-html40/struct/tables.html#h-11.2>`__. A
        working draft of the HTML 5 spec can be found `here
        <https://html.spec.whatwg.org/multipage/tables.html>`__. It contains the
        latest information on table attributes for the modern web.

    parse_dates : bool, optional
        See :func:`~read_csv` for more details.

    thousands : str, optional
        Separator to use to parse thousands. Defaults to ``','``.

    encoding : str, optional
        The encoding used to decode the web page. Defaults to ``None``.``None``
        preserves the previous encoding behavior, which depends on the
        underlying parser library (e.g., the parser library will try to use
        the encoding provided by the document).

    decimal : str, default '.'
        Character to recognize as decimal point (e.g. use ',' for European
        data).

    converters : dict, default None
        Dict of functions for converting values in certain columns. Keys can
        either be integers or column labels, values are functions that take one
        input argument, the cell (not column) content, and return the
        transformed content.

    na_values : iterable, default None
        Custom NA values.

    keep_default_na : bool, default True
        If na_values are specified and keep_default_na is False the default NaN
        values are overridden, otherwise they're appended to.

    displayed_only : bool, default True
        Whether elements with "display: none" should be parsed.

    extract_links : {{None, "all", "header", "body", "footer"}}
        Table elements in the specified section(s) with <a> tags will have their
        href extracted.

        .. versionadded:: 1.5.0

    dtype_backend : {{'numpy_nullable', 'pyarrow'}}, default 'numpy_nullable'
        Back-end data type applied to the resultant :class:`DataFrame`
        (still experimental). Behaviour is as follows:

        * ``"numpy_nullable"``: returns nullable-dtype-backed :class:`DataFrame`
          (default).
        * ``"pyarrow"``: returns pyarrow-backed nullable :class:`ArrowDtype`
          DataFrame.

    Returns
    -------
    dfs
        A list of DataFrames.

    See Also
    --------
    read_csv : Read a comma-separated values (csv) file into DataFrame.

    Notes
    -----
    Before using this function you should read the :ref:`gotchas about the
    HTML parsing libraries <io.html.gotchas>`.

    Expect to do some cleanup after you call this function. For example, you
    might need to manually assign column names if the column names are
    converted to NaN when you pass the `header=0` argument. We try to assume as
    little as possible about the structure of the table and push the
    idiosyncrasies of the HTML contained in the table to the user.

    This function searches for ``<table>`` elements and only for ``<tr>``
    and ``<th>`` rows and ``<td>`` elements within each ``<tr>`` or ``<th>``
    element in the table. ``<td>`` stands for "table data". This function
    attempts to properly handle ``colspan`` and ``rowspan`` attributes.
    If the function has a ``<thead>`` argument, it is used to construct
    the header, otherwise the function attempts to find the header within
    the body (by putting rows with only ``<th>`` elements into the header).

    Similar to :func:`~read_csv` the `header` argument is applied
    **after** `skiprows` is applied.

    This function will *always* return a list of :class:`DataFrame` *or*
    it will fail, e.g., it will *not* return an empty list.

    <io.read_html>` for some examples of reading in HTML tables.
