Pankaj Kumar Malviya , Here i did sum of the all passengers whose Fare is lessthan8 by adding extra column. import pandas as pd df = pd.read_csv('https://sololearn.com/uploads/files/titanic.csv') df['lessthan8']= df['Fare'] < 8 is_less_8 = pd.Series(df['lessthan8']) print(sum(df[is_less_8]['Fare'].values))
