Course overview

This course is designed to equip you with the skills to gather and analyze data from the web like a pro. We start by introducing the basics of API structures, then progress to advanced data retrieval and analysis techniques. Our curriculum covers essential Python tools like the requests library, JSON data handling, data filtering, error management, authentications, and web scraping methods. By the end of this course, you’ll be adept at extracting and analyzing data directly from web pages and integrating it with Pandas for thorough analysis and visualization. We believe in practical learning—each lesson is tailored to real-world applications. This way, you’ll not only enhance your skills but also gain a deep understanding of AI’s practical aspects.

Best of all, you’ll learn by doing—you’ll write code, receive feedback directly in your browser, and apply your skills to several guided projects involving realistic scenarios. This hands-on approach will help you build your portfolio and prepare for your next interview. By the time you complete this course, you’ll be an expert at sourcing and manipulating data from various online sources, ready to take on analytical and development roles.

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!”
