How to use the investpy.funds.funds_as_df function in investpy

for example.

            In case the information was successfully retrieved, the :obj:`pandas.DataFrame` will look like::

                asset class | id | isin | issuer | name | symbol | tag
                ------------|----|------|--------|------|--------|-----
                xxxxxxxxxxx | xx | xxxx | xxxxxx | xxxx | xxxxxx | xxx

            Just like `investpy.funds.retrieve_funds()` :obj:`pandas.DataFrame` output, but instead of generating the
            CSV file, this function just reads it and loads it into a :obj:`pandas.DataFrame` object.

    Raises:
        IOError: if the funds file from `investpy` is missing or errored.
    """

    return fs.funds_as_df(country=country)
