How to filter out a row and column using str.split() in Python

Question

How do you filter the individual column to itself?

I want to make it from

   0      1     2  
Action Casual Indie
Action Casual  NaN
Action   NaN  Indie
Action   NaN   NaN

into

Action Casual  Indie
 True  True    False
 True  False   True
 True  False   False

Your help will be much appreciated!

You can try this:

import pandas as pd

df = pd.DataFrame([['Action', 'Casual', 'NaN'], ['Action', 'NaN', 'Indie'], ['Action', 'NaN', 'NaN']], columns=['Action', 'Casual', 'Indie'])

df = df.apply(lambda x: x == x.name)
