How to drop rows of Pandas DataFrame whose value in a certain column is NaN

Question

I have this DataFrame and want only the records whose EPS column is not NaN:

>>> df
                 STK_ID           


        

Answer 1

I know this has already been answered, but just for the sake of a purely pandas solution to this specific question as opposed to the general description from Aman (which was wonderful) and in case anyone else happens upon this:

import pandas as pd
df = df[pd.notnull(df['EPS'])]
