In this video we'll learn three ways to add new columns to your dataframes with Pandas.
I'll show you how to add columns using a Python List.
I'll also show you how to add columns using the insert() and the assign() function.
Insert allows you to add a column anywhere, while assign creates a whole new dataframe with a new column added to it.
I'll also show you how to add default values to your new columns, as well as null values.
