Challenge 3: Cleaning data

“

- [Instructor] Here's a challenge to practice cleaning the data. We're looking at our airline data, and we've discovered that there's some things that need cleaning. So first we're going to use a custom split to change the Airline Description into the Airline and the Airline Code. Second, we're then going to go through the Airline and group all of the values together because Southwest has several different spellings. Finally, exclude any of the other data that looks incorrect. This should take you around five minutes.
