Looking to beef up your Python programming skills? In addition to our interactive online programming and data science courses, our blog also features many free Python tutorials on topics including everything from for loops to machine learning.

Whether you want to brush up on your web scraping skills, review linear regression, beef up your data viz designs, or get better at cleaning your data, you'll find tutorials here that can help!

First things first, though: these articles can help you get your Python learning journey off on the right foot:

Free Interactive Python Courses

If you're just getting started on your Python journey, the best thing you can do is give yourself a great foundation in the fundamentals. Our introductory Python courses are free, interactive, and will allow you to apply what you're learning as you learn it. You don't need any prior programming experience, and by the time you finish, you'll have built a real-world data science project from the ground up using your new Python skills!

Beginning Python Tutorials

If you're at an early stage in your Python journey, these tutorials will help you solidify your command of basic concepts like lists, dictionaries, for loops, functions, and more. If you've never written a line of code before, we'd recommend you start with our Python Fundamentals course, which will help you learn Python from scratch. But if you've already spent a little time learning Python, these tutorials will help you go deeper and reinforce the skills you've already learned.

Python Tools

If you're going to do Python programming, particularly for data science, it helps to know the best tools to use. These Jupyter Notebooks tutorials will take you from a notebooks newbie to an expert who knows all the tips, tricks, and shortcuts. 

Working With Data

If you want to do data analysis in Python, you'll need to be able to access, collect, and manipulate data. These Python tutorials will walk you through various aspects of data collection and manipulation in Python, including web scraping, working with various APIs, concatenating data sets, and more. Or go hands-on with our SQL, web scraping, and API courses for data science.

Data Cleaning Tutorials

Machine learning may be the part of data science that gets all the headlines, but the reality is that most data scientists say they spend more time cleaning data than doing any other single task. These Python data cleaning tutorials will help you beef up your data cleaning and data munging skills by walking you through the process of scrubbing data for a variety of projects. Want to take things to the next level? Check out our introductory and advanced data cleaning courses.
