You can make your own class on top to get the behaviour that you want and then use it wherever you need:

class rTable(pd.DataFrame):
    def rloc(self, *args, **kwargs):
        output = self.copy()
        if len(kwargs) > 0:
            for k,v in kwargs.items():
                output = output.loc(axis=0)[lambda x: x[k] == v]
        if len(args) > 0:
            output = output.loc(axis=1)[args]
        return output
df = rTable.from_records([
        {"who": "the pro", 
         “able_to”: "add a method to a class"},
        {"who": "the noob", 
         “able_to”: “copy tricks from stackexchange”}])
df.rloc("who", able_to='add a method to a class')

you will see the filtered dataframe com out.

Enjoy!
