![Working with APIs in Python [For Your Data Science Project]](https://i.ytimg.com/vi/fklHBWow8vE/mqdefault.jpg "Working with APIs in Python [For Your Data Science Project]
We’re going to be working with the Youtube API to collect video statistics from my channel using the requests python library to make an API call and save it as a pandas dataframe. Working with APIs is a necessary skillset for all data scientists and should be incorporated into your data science projects. I talk about the one data science project you’ll ever need in this video https://bit.ly/3rEt6WG so we’ll start with the first step and learn how to work with APIs in python to collect our data.
The python notebook and links to resources are located in this Github repo: https://github.com/Strata-Scratch/api-youtube/blob/main/README.md

![How To Handle Multicollinearity and Feature Selection [DoorDash Data Science Project]](https://i.ytimg.com/vi/gh5JzALBQvU/mqdefault.jpg "How To Handle Multicollinearity and Feature Selection [DoorDash Data Science Project]
In this video, well give you a brief introduction to multicollinearity and feature selection, and show you how to solve the problem using a variety of methods. Well be using the DoorDash data science project to demonstrate how to apply these concepts in practice. In addition, well use the Random Forest regression method to determine which features are most important for predicting delivery times.
