Before we learn about the money, let’s get this question out of the way:
What Does a Data Scientist Do?
Data scientists use data to find quantifiable answers to questions that often need to be found as well!
For example, they not only find the answer to the question “How can company ABC make more money?” Instead, they may find that a better question to ask would be: “Who are the top 20% of the clients that bring 80% of the revenue, and what do they want in the first place?”
Top 15 Skills of a Data Scientist
Data scientists often have a broad mix of skills such as:
- Business acumen
- Statistics & math
- Computer science
- Programming and scripting
- Data visualization
- Machine learning and artificial intelligence
- Cloud Computing
- Databases and SQL
- Deep learning
- Structured and logical thinking
- Curiosity and a willingness to learn
- Dashboard creation
- Communication and presentation
- Big data frameworks and distributed systems
- Graph theory
And a good deal of common sense and intuitive understanding of where real-world value can be found. This requires a lot of experience—but you can get started quickly and gain the experience over time in practice.
Now that you know what a data scientist is and what skills you need, let’s have a look at what you can earn as a data scientist next!

Okay, but what do you need to do to get there? What are the skill requirements and qualifications to make you become a professional developer in the area you desire?
Let’s find out next!
General Qualifications of Professionals
StackOverflow performs an annual survey asking professionals, coders, developers, researchers, and engineers various questions about their background and job satisfaction on their website.
Interestingly, when aggregating the data of the developers’ educational background, a good three quarters have an academic background.
Here’s the question asked by StackOverflow (source):
Which of the following best describes the highest level of formal education that you’ve completed?
However, if you don’t have a formal degree, don’t fear! Many of the respondents with degrees don’t have a degree in their field—so it may not be of much value for their coding careers anyways.
Also, about one out of four don’t have a formal degree and still succeeds in their field! You certainly don’t need a degree if you’re committed to your own success!
Freelancing vs Employment Status
The percentage of freelance developers increases steadily. The fraction of freelance developers has already reached 11.21%!
This indicates that more and more work will be done in a more flexible work environment—and fewer and fewer companies and clients want to hire inflexible talent.
Here are the stats from the StackOverflow developer survey (source):
Do you want to become a professional freelance developer and earn some money on the side or as your primary source of income?

Other Programming Languages Used by Professional Developers
The StackOverflow developer survey collected 58000 responses about the following question (source):
Which programming, scripting, and markup languages have you done extensive development work in over the past year, and which do you want to work in over the next year?
These are the languages you want to focus on when starting out as a coder:
And don’t worry—if you feel stuck or struggle with a nasty bug. We all go through it. Here’s what SO survey respondents and professional developers do when they’re stuck:

Where to Go From Here?
Enough theory. Let’s get some practice!
Coders get paid six figures and more because they can solve problems more effectively using machine intelligence and automation.
To become more successful in coding, solve more real problems for real people. That’s how you polish the skills you really need in practice. After all, what’s the use of learning theory that nobody ever needs?
You build high-value coding skills by working on practical coding projects!
Do you want to stop learning with toy projects and focus on practical code projects that earn you money and solve real problems for people?
🚀 If your answer is YES!, consider becoming a Python freelance developer! It’s the best way of approaching the task of improving your Python skills—even if you are a complete beginner.
