    Create valid Python identifiers from any string.

    Check if name contains any special characters. If it contains any
    special characters, the special characters will be replaced by
    a special string and a prefix is added.

    Raises
    ------
    SyntaxError
        If the returned name is not a Python valid identifier, raise an exception.
        This can happen if there is a hashtag in the name, as the tokenizer will
        than terminate and not find the backtick.
        But also for characters that fall out of the range of (U+0001..U+007F).

    Clean up a column name if surrounded by backticks.

    Backtick quoted string are indicated by a certain tokval value. If a string
    is a backtick quoted token it will processed by
    :func:`_create_valid_python_identifier` so that the parser can find this
    string when the query is executed.
    In this case the tok will get the NAME tokval.

    Parameters
    ----------
    tok : tuple of int, str
        ints correspond to the all caps constants in the tokenize module

    Returns
    -------
    tok : Tuple[int, str]
        Either the input or token or the replacement values

    Function to emulate the cleaning of a backtick quoted name.

    The purpose for this function is to see what happens to the name of
    identifier if it goes to the process of being parsed a Python code
    inside a backtick quoted string and than being cleaned
    (removed of any special characters).

    Parameters
    ----------
    name : hashable
        Name to be cleaned.

    Returns
    -------
    name : hashable
        Returns the name after tokenizing and cleaning.

    Notes
    -----
        For some cases, a name cannot be converted to a valid Python identifier.
        In that case :func:`tokenize_string` raises a SyntaxError.
        In that case, we just return the name unmodified.

        If this name was used in the query string (this makes the query call impossible)
        an error will be raised by :func:`tokenize_backtick_quoted_string` instead,
        which is not caught and propagates to the user level.

    Creates a token from a backtick quoted string.

    Moves the token_generator forwards till right after the next backtick.

    Parameters
    ----------
    token_generator : Iterator[tokenize.TokenInfo]
        The generator that yields the tokens of the source string (Tuple[int, str]).
        The generator is at the first token after the backtick (`)

    source : str
        The Python source code string.

    string_start : int
        This is the start of backtick quoted string inside the source string.

    Returns
    -------
    tok: Tuple[int, str]
        The token that represents the backtick quoted string.
        The integer is equal to BACKTICK_QUOTED_STRING (100).

    Parameters
