df[df['A'] > 2]['B'] = new_val # new_val not set in dfThe warning offers a suggestion to rewrite as follows:
df.loc[df['A'] > 2, 'B'] = new_valHowever, this doesn't fit your usage, which is equivalent to:
df = df[df['A'] > 2]
df['B'] = new_valWarning we got on trying to rewrite certain dataframe rows, which led us to use .loc.
