Why Dataquest?
The Dataquest platform in a nutshell.
It's hard to learn by watching other people code.
On Dataquest, you'll be doing all of the coding yourself — right from your browser window!
At each step of your journey, you'll be asked to apply what you're learning by writing code, and your answers are checked instantly to make sure you're on the right track.
Throughout this path, you'll go from writing basic Python snippets like for loops to working with popular data science packages like pandas and scikit-learn.
And as you do it all, you'll be working with real-world data to solve real data science problems.
