“The intuitive learning process on Dataquest was refreshing. I never became frustrated with technical problems, or had to waste time watching a video before getting on with coding. If I hit a wall, the community was there to help.”

Course overview

In this course, you’ll learn how to navigate the filesystem, how to alter permissions for different users, and how to create and run a Python script from the command line. You’ll also learn how to use the terminal on UNIX machines and how to use the command line’s powerful text processing tools like awk and sed. The lack of a graphical user interface (GUI) also makes the command line faster than other approaches for many tasks.
Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. When you finish the course, you’ll have enough hands-on practice that you’ll be comfortable using the command line in your day-to-day data analysis tasks.

Aaron Melton

Business Analyst at Aditi Consulting

“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!”
