![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.
