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

But for any future bypassers you could mention that df = df[df.line_race != 0] doesn't do anything when trying to filter for None/missing values.

Does work:

df = df[df.line_race != 0]

Doesn't do anything:

df = df[df.line_race != None]

Does work:

df = df[df.line_race.notnull()]
