'How to return a DataFrame when using pandas.apply()
I'm trying to get a concated DataFrame using pandas.apply(), there is a demo below:
Just like the code shown, the apply() returns a Series instead of a concated DataFrame that I expected, how can I solve it?

Tecnically, they do the same thing but the applymap apply your function to the entire Dataframe and it returns a Dataframe no matter what happens.
