ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

This error occurs when trying to use a pandas Series object as a boolean expression, which can result in ambiguous truth values.
To resolve this error, you can use one of the suggested methods to explicitly convert the Series object to a boolean:
- `a.empty`: returns True if the Series is empty, and False otherwise.
- `a.bool()`: returns True if all elements in the Series are True, and False otherwise. Raises an error if the Series contains non-boolean values.
- `a.item()`: returns the single value in a Series with exactly one element. Raises an error if the Series has zero or more than one element.
- `a.any()`: returns True if any element in the Series is True, and False otherwise.
- `a.all()`: returns True if all elements in the Series are True, and False otherwise.
Choose the appropriate method based on your use case and the expected behavior of the Series.
