I need to filter some information from my data grid, such as average surviving age and proportion of living men and women
I try with this
tit.groupby(by=['Survived'])['Yes']
But I can't filter this way
You are probably working with the titanic dataset, and for this filter you don't need groupby.
First filter:
tit.loc[tit['Survived'] == 'Yes']
Second filter:
tit.loc[(tit['Survived'] == 'Yes') & (tit['Sex'] == 'Women')]
