In this video, we'll cover the powerful aggregate and group by functions in Python and show you how to use them to solve common coding interview questions. You will learn how to use the aggregate function to perform calculations on a group of data, such as finding the mean, median, or sum. We will also demonstrate how to use the group by function to group and analyze data by specific columns or attributes.

![Exploratory Data Analysis For An Uber Python Data Science Project [Part 1]](https://i.ytimg.com/vi/ZOthTms86Bw/mqdefault.jpg "Exploratory Data Analysis For An Uber Python Data Science Project [Part 1]
In this video, well take you through a data project from Uber called Partner Business Modeling. Well delve into the details of exploring and cleaning up the dataset. Well use popular Python libraries such as Pandas, NumPy, and Matplotlib to manipulate, analyze and visualize the data. And showcase how custom functions can be used to create bar graphs and how to clean and change rows using the apply method.
