Categories of errors
In the video exercise, you saw how to address common problems affecting categorical variables in your data, including white spaces and inconsistencies in your categories, and the problem of creating new categories and mapping existing ones to new ones.
To get a better idea of the toolkit at your disposal, you will be mapping functions and methods from pandas
and Python used to address each type of problem.
