With Python sitting in that No. 1 spot, it’s no wonder why gaining the necessary skills to master the language is an increasingly popular goal for entry-level data scientists and developers alike.
For those interested in working in artificial intelligence, machine learning, bioinformatics, full-stack web development, and engineering, adding Python to your toolbox can be effective for building a solid career path across many different industries.
What is Python?
Python is a computer programming language that developers use to create websites and software, conduct data analysis, and automate tasks. It’s considered a general-purpose language, which means there are a lot of different applications and situations in which it can be used because it isn’t specialized for any specific problems.
It was developed by Guido van Rossum in 1991, and the name “Python” is a nod to the British comedy group Monty Python.
The good news is that it is easy to learn and read and has a large community of support. That’s according to Wade Fagen-Ulmschneider, a teaching associate professor of computer science at the University of Illinois. He tells Fortune that his Introduction to Data Science Using Python, which started in 2019 with just 16 students, has multiplied over 100 times to 1,659 students at the time of publication.
“A lot of people compare Python to other programming languages like C, C++, or even Java,” Fagen-Ulmschneider says. “But if you look at those languages, you’ll see lots of syntaxes—lots of curly braces, lots of parentheses, lots of square brackets—things that mean something to a programmer but don’t mean anything to somebody with no concept of programming.”
He explains that with Python, you can achieve more with fewer lines of code, symbols, and keywords, leading to faster development. In fact, he thinks you can write your first program in a weekend’s-time.
When it comes to Python courses, Fortune has you covered with programs that can not only help you toy around with the language but also get you on the fast track to becoming a Python developer.
These classes range from free and beginner-friendly to more mid-level, offering certifications or are offered by credible organizations. Note: There is no single best course out there—so consider which best caters to your personal needs, experience level, and career trajectory.
4 free Python courses
These four free courses teach Python at an introductory level. Each varies on program length but offers non-specialized, general coursework.
1. Google’s Python Class
This is the course Google has its employees take to introduce them to Python concepts. This free class contains a tutorial on how to set your computer up for coding and teachings on strings, lists, regular Python expressions, and its common utilities.

Should I take a Python course that offers a certificate?
When researching courses, you might come across a few that offer certifications. As such, you might ask yourself, “Do I need a Python certification?” and “What’s the best Python certificate?”
The answer isn’t so clear-cut. When asked about classes that offer certificates, Fagen-Ulmschneider expressed a mixed view. “On one hand, certificates are a great way to showcase credentials on platforms like LinkedIn or a resume. But having a strong GitHub page showing projects that you’ve worked on would be a stronger signal than any certificate alone,” he says.
If your heart is set on certifications, this is a course path we like:

4 things to consider before enrolling in a Python course
If there’s one thing that this article can teach you, it’s that there are a lot of courses online to choose from. Some might sound great, but they might not give you the results you’re looking for.
Fagen-Ulmschneider says there are four things you should think about before either swiping your credit card or wasting your time with any Python course:
- Credibility: Make sure the course is created by someone with credibility in the field, either through industry experience building large platforms or through teaching experience where many students have found value.
- Fundamentals and hands-on practice: Ensure the course starts with the basics and has hands-on programming practice rather than just demonstration videos. Fagen-Ulmschneider says, “Programming is best learned through doing.”
- Guidance: Look for a course that offers one-on-one guidance from beginning to end. “A helping hand can help you stay motivated throughout the learning process,” he explains.
- Check other free resources: Before committing to anything, consider free options like Khan Academy or freeCodeCamp. He says, “Many of the students I work with got their hands wet in programming by watching some YouTube videos and looking at free content.”
So, what’s the best Python course to take?
The best Python course to take is the one that best suits your wants, needs, and budget. While YouTube offers a seemingly infinite amount of Python content, a structured learning course can give you the backbone to push your coding journey forward to the next level.
Whether you want to pay for a course, audit one from a university, or take a free online one from a credible company, there’s an option for everyone. And if you’re still on the fence about learning Python at all, consider this advice:
“If you’ve never done programming before, Python almost feels like magic,” Fagen-Ulmschneider says. “It is the most beginner-friendly language right now. Within a few hours, you’ll have something powerful running. I would recommend playing around with it.”
He says you can use Google’s Colaboratory, an online code editor, to access some resources and manipulate the syntax yourself.
