The world is becoming increasingly data-driven. Data is one of the most valuable resources a company can have, but without a data scientist, it’s just numbers.

Businesses everywhere are looking for professionals who can turn raw data into clear insights. According to the U.S. Bureau of Labor Statistics, jobs for data scientists are expected to grow by 34% between 2024 and 2034, much faster than most careers.

Becoming a data scientist takes more than coding or statistics. It’s a mix of math, computer science, business knowledge, and communication skills. This combination makes the role both challenging and in demand.

I know it’s possible to get there. I started with a history degree and later became a machine learning engineer, data science consultant, and founder of Dataquest. With the right plan, you can do it too.

What is a Data Scientist?

A data scientist is someone who uses data to answer questions and solve problems. They collect large amounts of information, clean it, analyze it, and turn it into something actionable.

They use tools like Python, R, and SQL to manage and explore data. They apply statistics, machine learning, and data visualization to find patterns, understand trends, and make predictions.

Some data scientists build tools and systems for users, while others focus on helping businesses make better decisions by predicting future outcomes.

What Do Data Scientists Do?

Data scientists wear many hats. Their work depends on the company and the type of data they handle, but the goal is always the same: to turn data into useful insights that help people make data-driven decisions.

Data science powers everything from the algorithm showing you the next TikTok video to how ChatGPT answers questions to how Netflix recommends shows.

Some data scientist responsibilities include:

• Collect and clean data from databases, APIs, and spreadsheets to prepare it for analysis.
• Analyze and explore data to find trends, patterns, and relationships that explain what’s happening.
• Build machine learning models and make predictions to forecast sales, detect fraud, or recommend products.
• Visualize and communicate insights through charts and dashboards using tools like Tableau, Matplotlib, or Power BI.
• Automate and improve systems by creating smarter processes, optimizing marketing campaigns, or building better recommendation engines.

In short, they help businesses make smarter decisions and work faster.

The Wrong and Right Way

When I started learning data science, I followed every online guide I could find, but I ended up bored and without real skills to show for it. It felt like a teacher handing me a pile of books and telling me to read them all.

Eventually, I realized I learn best when I’m solving problems that interest me. So instead of memorizing a checklist of skills, I began building real projects with real data. That approach kept me motivated and mirrored the work I’d actually do as a data scientist.

With that experience, I created Dataquest to help others learn the same way: by doing. But courses alone aren’t enough. To succeed, you need to learn how to think, plan, and execute effectively. This guide will show you how.

How to Become a Data Scientist:

• Step 1: Earn a Degree (Recommended, Not Required)
• Step 2: Learn the Core Skills
• Step 3: Question Everything and Find Your Niche
• Step 4: Build Projects
• Step 5: Share Your Work
• Step 6: Learn From Others
• Step 7: Push Your Boundaries
• Step 8: Start Looking for a Job

Now, let’s go over each of these one by one.

Step 1: Earn a Degree (Recommended, Not Required)

Most data scientists start with a degree in a technical field. According to Zippia, 51% of data scientists hold a bachelor’s degree, 34% a master’s, and 13% a doctorate.

A degree helps you build a solid foundation in math, statistics, and programming. It also shows employers that you can handle complex concepts and long-term projects.

Step 3: Question Everything and Find Your Niche

The data science and data analytics field is appealing because you get to answer interesting questions using actual data and code. These questions can range from “Can I predict whether a flight will be on time?” to “How much does the U.S. spend per student on education?"

To answer these questions, you need to develop an analytical mindset.

The best way to develop this mindset is to start by analyzing news articles. First, find a news article that discusses data. Here are two great examples: Can Running Make You Smarter? or Is Sugar Really Bad for You?

Then, think about the following:

• How they reach their conclusions given the data they discuss
• How you might design a study to investigate further
• What questions you might want to ask if you had access to the underlying data

Some articles, like this one on gun deaths in the U.S. and this one on online communities supporting Donald Trump, actually have the underlying data available for download. This allows you to explore even deeper.

You could do the following:

• Download the data, and open it in Excel or an equivalent tool
• See what patterns you can find in the data by eyeballing it
• Does the data support the conclusions of the article? Why or why not?
• What additional questions can you use the data to answer?

Here are some good places to find data-driven articles:

• FiveThirtyEight
• New York Times
• Vox
• The Intercept

Think About What You’re Interested In

After a few weeks of reading articles, reflect on whether you enjoyed coming up with questions and answering them. Becoming a data scientist is a long road, and you need to be very passionate about the field to make it all the way. What is the industry that attracts you the most?

Perhaps you don't enjoy the process of coming up with questions in the abstract, but maybe you enjoy analyzing healthcare or finance data. Find what you're passionate about, and then start viewing it through an analytical lens.

Personally, I was very interested in stock market data, which motivated me to build a model to predict the market.

If you want to put in the months of hard work necessary to learn data science, working on something you’re passionate about will help you stay motivated when you face setbacks.

Step 4: Build Projects

As you’re learning the basics of coding, start applying your knowledge to get practical experience. Coursework isn't enough. Projects help you practice real-world techniques and develop the practical skills employers look for in the job market. It's a great way to test your knowledge.

Your projects don’t have to be complex. For example, you could analyze Super Bowl winners to find patterns, study weather data to predict rainfall, or explore movie ratings to see what drives popularity. The goal is to take an interesting dataset, ask good questions, and use code to answer them.

As you build projects, keep these points in mind:

• Most real-world data science work involves data cleaning and preparation.
• Simple machine learning algorithms like linear regression or decision trees are powerful starting points.
• Focus on improving how you handle messy data, visualize insights, and communicate results. These are the techniques that make you stand out.
• Everyone starts somewhere. Even small projects can show your creativity, logic, and problem-solving skills.

Building projects early helps you get practical experience that will make your portfolio much stronger when entering the job market.

As you're learning the basics of data science, you should start building projects that answer interesting questions that will showcase your data science skills.

Start a Simple Blog

Besides uploading projects to GitHub, start a blog. Writing about what you learn helps you understand topics better and spot what you’ve missed. Teaching others is one of the fastest ways to master a concept.

When I was learning data science, writing blog posts helped me do the following:

• Capture interest from recruiters
• Learn concepts more thoroughly (the process of teaching really helps you learn)
• Connect with peers

You can write about:

• Explaining data science concepts in simple terms
• Walking through your projects and findings
• Sharing your learning journey

Here’s an example of a visualization I made on my blog many years ago that tries to answer the question: do the Simpsons characters like each other?

Step 6: Learn From Others

After you've started to build an online presence, it's a good idea to start engaging with other data scientists. You can do this in-person or in online communities.

Here are some good online communities:

Engaging in online communities is a good way to do the following:

• Find other people to learn with
• Enhance your profile and find opportunities
• Strengthen your knowledge by learning from others

You can also engage with people in person through Meetups. In-person engagement can help you meet and learn from more experienced data scientists in your area. Take all the opportunities to learn.

Step 7: Push Your Boundaries

What kind of data scientists do organizations want to hire? The ones that find critical insights that save them money or make their customers happier. You have to apply the same process to learning, keep searching for new questions to answer, and keep answering harder and more complex questions.

If you look back on your projects from a month or two ago, and you don’t see room for improvement, you probably aren't pushing your boundaries enough. You should be making strong progress every month, and your work should reflect that. Interesting projects will make you stand out among applicants.

Here are some ways to push your boundaries and learn data science faster:

• Try working with a larger dataset
• Start a data science project that requires knowledge you don't have
• Try making your project run faster
• Teach what you did in a project to someone else

Step 8: Start Looking for a Job

Once you’ve built a few projects and learned the core skills, it’s time to start applying, not “someday,” but now. Don’t wait until you feel completely ready. The truth is, no one ever does.

Start with internships, entry-level roles, or freelance gigs. These give you real-world experience and help you understand how data science works in a business setting. Even if the job description looks intimidating, apply anyway. Many employers list “ideal” requirements, not must-haves.

Don’t get stuck studying forever. The best learning happens on the job. Every interview, every project, and every rejection teaches you something new.

You never know, the opportunity that looks like a long shot might be the one that launches your data science career. The more practical experience you gain, the deeper your knowledge becomes.

When I first tried to learn Python, I spent months memorizing rules, staring at errors, and questioning whether coding was even right for me. Almost every beginner hits this wall.

Thankfully, there’s a better way to learn Python. This guide condenses everything I’ve learned over the past decade (the shortcuts, mistakes, and proven methods) into a simple, step-by-step approach.

I know it works because I’ve been where you are. I started with a history degree and zero coding experience. Ten years later, I’m a machine learning engineer, a data science consultant, and the founder of Dataquest.

Let’s get started.

The Problem With Most Learning Resources

Most Python courses are broken. They make you memorize rules and syntax for weeks before you ever get to build anything interesting.

I know because I went through it myself. I had to sit through boring lectures, read books that would put me to sleep, and follow exercises that felt pointless. All I wanted to do was jump straight into the fun parts. Things like building websites, experimenting with AI, or analyzing data.

No matter how hard I tried, Python felt like an alien language. That’s why so many beginners give up before seeing results.

But there’s a more effective approach that keeps you motivated and gets results faster.

A Better Way

Think of learning Python like learning a spoken language. You don’t start by memorizing every rule. Instead, you begin speaking, celebrate small wins, and learn as you go.

The best advice I can give is to learn the basics, then immediately dive into a project that excites you. That is where real learning happens. For example, you could build a tool, design a simple app, or explore a creative idea. Suddenly, what once felt confusing and frustrating now becomes fun and motivating.

This is exactly how we built Dataquest. Our Python courses get you coding fast, with less memorization and more doing. You’ll start writing Python code in a matter of minutes.

Now, I’ve distilled this approach into five simple steps. Follow them, and you will learn Python faster, enjoy the process, and build projects you can be proud of.

How to Learn Python from Scratch in 2025

9 Learning Tips for Python Beginners

Learning Python from scratch can feel overwhelming at first, but a few practical strategies can make the process smoother and more enjoyable. Here are some tips to help you stay consistent, motivated, and effective as you learn:

1. Practice Consistently

Consistency beats cramming. Even dedicating 30–60 minutes a day to coding will reinforce your understanding faster than occasional marathon sessions. Daily practice helps concepts stick and makes coding feel natural over time.

2. Build Projects Early

Don’t wait until you “know everything.” Start building small projects from the beginning. Even simple programs, like a calculator or a to-do list app, teach you more than memorizing syntax ever will. Projects also keep learning fun and tangible.

3. Break Problems Into Smaller Steps

Large problems can feel intimidating. Break them into manageable steps and tackle them one at a time. This approach helps you stay focused and reduces the feeling of being stuck.

4. Experiment and Make Mistakes

Mistakes are part of learning. Try changing code, testing new ideas, and intentionally breaking programs to see what happens. Each error is a lesson in disguise and helps you understand Python more deeply.

5. Read Code from Others

Explore [open-source projects](https://pypi.org/), tutorials, and sample code. Seeing how others structure programs, solve problems, and write functions gives you new perspectives and improves your coding style.

6. Take Notes

Writing down key concepts, tips, and tricks helps reinforce learning. Notes can be a quick reference when you’re stuck, and they also provide a record of your progress over time.

7. Use Interactive Learning

Interactive platforms and exercises help you learn by doing, not just by reading. Immediate feedback on your code helps you understand mistakes and internalize solutions faster.

8. Set Small, Achievable Goals

Set realistic goals for each session or week. Completing these small milestones gives a sense of accomplishment and keeps motivation high.

9. Review and Reflect

Regularly review your past projects and exercises. Reflecting on what you’ve learned helps solidify knowledge and shows how far you’ve come, which is especially motivating for beginners.

7 Common Beginner Mistakes in Python

Learning Python is exciting, but beginners often stumble on the same issues. Knowing these common mistakes ahead of time can save you frustration and keep your progress steady.

Mistake	Description	Solution
1. Overthinking Code	Beginners often try to write complex solutions right away.	Break tasks into smaller steps and tackle them one at a time.
2. Ignoring Errors	Errors are not failures—they're learning opportunities. Skipping them slows progress.	Read error messages carefully, Google them, or ask in forums like StackOverflow. Debugging teaches you how Python really works.
3. Memorizing Without Doing	Memorizing syntax alone doesn't help. Python is learned by coding.	Immediately apply what you learn in small scripts or mini-projects.
4. Not Using Version Control	Beginners often don't track their code changes, making it hard to experiment or recover from mistakes.	Start using Git early. Even basic GitHub workflows help you organize code and showcase projects.
5. Jumping Between Too Many Resources	Switching between multiple tutorials, courses, or books can be overwhelming.	Pick one structured learning path first, and stick with it until you've built a solid foundation.
6. Avoiding Challenges	Sticking only to easy exercises slows growth.	Tackle projects slightly above your comfort level to learn faster and gain confidence.
7. Neglecting Python Best Practices	Messy, unorganized code is harder to debug and expand.	Follow simple practices early: meaningful variable names, consistent indentation, and writing functions for repetitive tasks.
