Course overview

In this course, you’ll expand your Python for data engineering knowledge. Using real-world data from the Museum of Modern Art, you’ ll learn how to prepare text data, introduce uniformity into a messy dataset, and more. You’ll also explore object-oriented programming (OOP) and how it powers Python. Finally, you’ll learn new and exciting Python coding concepts for data engineering.

Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser.

“Dataquest starts at the most basic level, so a beginner can understand the concepts. I tried learning to code before, using Codecademy and Coursera. I struggled because I had no background in coding, and I was spending a lot of time Googling. Dataquest helped me actually learn.”


Jessica Ko

Machine Learning Engineer at Twitter

“I liked the interactive environment on Dataquest. The material was clear and well organized. I spent more time practicing then watching videos and it made me want to keep learning.”


Victoria E. Guzik

Associate Data Scientist at Callisto Media

“I really love learning on Dataquest. I looked into a couple of other options and I found that they were much too handhold-y and fill in the blank relative to Dataquest’s method. The projects on Dataquest were key to getting my job. I doubled my income!”
