How to add an empty column to a dataframe?

In pandas, you can add an empty column to a DataFrame using the assign() method or the insert() method.

Here is an example using the assign() method:

This will add a column named 'C' with all values as None to the dataframe.

You can also use the insert() method to add an empty column to a specific location in the DataFrame:
