Trouble passing in lambda to apply for pandas DataFrame
Note there is no axis param for a Series.apply call, as distinct to a DataFrame.apply call.
Series.apply(func, convert_dtype=True, args=(), **kwds)
func : functionconvert_dtype : boolean, default TrueTry to find better dtype for elementwise function results. If False, leave as dtype=objectargs : tuplePositional arguments to pass to function in addition to the valueThere is one for a df but it's unclear how you're expecting this to work when you're calling it on a series but you're expecting it to work on a row?
