“You get small lessons and can practice skills right away. It’s so convenient. Committing to Dataquest was an easy decision.”

Course overview

In our intermediate command line course, you’ll learn to improve your data analysis workflow with concepts such as piping and redirecting output into a file; searching files for a string; and cleaning, exploring, and consolidating data using the command line.

You’ll also learn to work with Jupyter console, an enhanced Python interpreter, to develop scripts. And you’ll learn how to clean and explore data using csvkit, a suite of command line tools for converting and working with CSV formats.

Then you’ll build a project that combines your Python data skills with your new command line expertise — you’ll write Python scripts to compute summary statistics and then run the scripts directly from the command line. When you finish this course, you’ll be able to add “UNIX Command Line” skills to your data science resume!

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!”
