filter columns where index value is 0
Question:
In a given dataframe:
I would like to filter those columns where values are 0 for index std.
Answers:
Use DataFrame.loc in boolean indexing – first select index std, compare and select all rows by : with filtered mask:
df1 = df.loc[:, df.loc['std'].eq(0)]
You can filter the std column for values that are equal to zero.
This could work: df = num_df.loc[num_df['std'] == 0]
