Pandas How to filter a Series

Question

I have a Series like this after doing groupby(\'name\') and used mean() function on other column

name
383      3.000000
663      1.000000
726      1.000000
7         


        

Answer 1

From pandas version 0.18+ filtering a series can also be done as below

test = {
383:    3.000000,
663:    1.000000,
726:    1.000000,
737:    9.000000,
833:    8.166667
}

pd.Series(test).where(lambda x : x!=1).dropna()
