Pandas GroupBy Count
Показать описание
This video will show you how to groupby count using Pandas. This is the first groupby video you need to start with.
Grouping your data and performing some sort of aggregations on your dataframe is one of the early questions you will seek an answer to as you learn Pandas. This video aims to quickly get you learning the mechanics of groupby in Pandas.
The key lesson to remember is that you first create a groupby object. Make sure to save the object in a variable we have access to. We then can use that variable or object over and over. In the case of this lesson, we use count.
The video ends by showing you how you can groupby multiple columns and still perform a count on the group. This is a skill you need to refine and that you will use quite often.
