AttributeError: 'DataFrame' object has no attribute 'mad' in Pandas 2.0+

Hi everyone,
I'm trying to calculate the Mean Absolute Deviation (MAD) from a Pandas DataFrame using the .mad() function. Here's my code:

python

importpandas as pd df = pd.DataFrame({'marks': [70, 75, 80, 85, 90]}) print("MAD (DataFrame):") print(df.mad())

But I'm getting the following error

AttributeError: 'DataFrame' object has no attribute 'mad'

I'm using Pandas version 2.0+.
