Deleting DataFrame row in Pandas based on column value

Question

I have the following DataFrame:

             daysago  line_race rating        rw    wrating
 line_date                                                 
 2007         


        

Answer 1

just to add another solution, particularly useful if you are using the new pandas assessors, other solutions will replace the original pandas and lose the assessors

df.drop(df.loc[df['line_race']==0].index, inplace=True)
