TypeError: can only perform ops with scalar values

问题

I would appreciate if you could let me know how to plot some informative charts for the table provided here.

For example, I need a bar chart for the column named "Domestic unlisted companies:Use of IFRSs by unlisted companies" which shows in how many jurisdictions IFRSs is permitted, not permitted and so on. Or, a bar chart for the "Audit report states compliance with IFRS" column.

Besides, I need a pie chart for the column with the title "Domestic listed companies" which shows in how many jurisdictions IFRSs is permitted, not permitted and so on.

tables = pd.read_html('https://www.iasplus.com/en/resources/ifrs-topics/use-of-ifrs', header = None)

df = tables[2]

df.columns = df.columns.get_level_values(0)  + ":" + df.columns.get_level_values(1)

sns.countplot( "Domestic unlisted companies:Use of IFRSs by unlisted companies", data=df)

Could you please let me know how to resolve this error?

Thanks in advance.
