How to Solve Pandas Error: nested renamer is not supported python

Problem Description
After running df.groupby([‘id’])[‘click’].agg({‘click_std’: ‘std’}).reset_index(), I get nested renamer is not supported python error

Solution
In the new Pandas version, the dictionary approach of {‘click_std’:’std’} has been abandoned in favor of df.groupby([‘id ‘])[‘click’].agg(click_std=’std’).reset_index() and then run successfully.
