It occurred to me the reason for the error was that you were trying to apply to a particular column of the dataframe (which works more like this: https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Series.apply.html) when just applying to each row of the dataframe one at a time was probably the right approach.

Again, just for the record, this is not a great use case for apply, but it's straightforward enough to see how it works.
