There are several exercises that focus on how to use a particular function and method. The functions are covered in detail by explaining the important parameters and how to use them. By completing this course, you will be able to do data analysis and manipulation with Pandas easily and efficiently.

Mastering Data Analysis with Python Pandas

## Using the `unique` and `nunique` functions

The columns in a `DataFrame` might be categorical or continuous. The categorical columns may have many distinct but finite numbers of values, whereas continuous ones can take infinitely many values. In this sense, the columns can be considered as either discrete or categorical random variables.

Checking the number of distinct values in a categorical column is an essential part of exploratory data analysis. The `nunique` function returns the number of distinct values in a column and the `unique` function actually shows the unique values. We can apply them to the product group column in the `sales`.
