Where can I practice Python with practical problems that help with both DSA and Data Science?

I'm currently learning Python and I want to improve my problem-solving skills. My main problem is that I can't find a good source of practical questions to practice regularly.

I'm looking for problems that:

  • Improve my Python fundamentals and logic
  • Gradually introduce DSA concepts
  • Are also useful for Data Science (lists, dictionaries, strings, data processing, files/JSON, etc.)
  • Start from beginner level and gradually become harder
  • Make me actually think and solve problems rather than just follow tutorials
  • Are useful for building real problem-solving ability

I don't necessarily want only competitive-programming-style questions. I'd prefer realistic and interesting problems that can help me understand how Python is actually used.

Where do you recommend I practice? Are there any websites, GitHub repositories, or structured problem sets that follow a good progression from beginner → intermediate?

If you are learning/working in Data Science, what type of Python problems would you recommend practicing?

**Confused About What to Focus on in Computer Engineering — DSA, Web Dev, Data Science, AI, etc.?**

I'm currently a 3rd-year Computer Engineering student and I'm confused about what I should focus on for my career.

I know DSA is important, but I don't want to limit myself to only traditional programming languages and regular DSA practice. I’m interested in exploring different domains like Web Development, Data Science, AI/ML, Cloud, Cybersecurity, etc.

I also want to explore a domain where I can actually build something interesting and different, especially projects that I could use for hackathons. I don't want to keep making the usual CRUD websites or basic projects. I want to learn the actual logic behind building something, solve real problems, and gain skills that are useful at an industry level.

So what domains would you recommend I explore as a Computer Engineering student?

What are some less-common/interesting technologies or domains where I could build unique hackathon projects while also learning valuable industry-level concepts?

Also, is DSA necessary for every domain, or are there career paths where I can focus more on other skills?

I'd really appreciate advice from people who are already working in the industry or have been through this stage.
