1. Why I Took This Course

After completing Python basics, I realized that real-world projects require a deeper understanding of topics like file handling, error management, object-oriented programming, and functional programming.

So, I decided to challenge myself and complete the Python Intermediate course on SoloLearn.

2. What I Learned

  • Collection Types: Sets, Tuples, Dictionaries
  • Error Handling: try-except blocks, handling unexpected errors gracefully
  • Functional Programming: lambda expressions, map/filter functions (still feels a bit tricky!)
  • Object-Oriented Programming: Creating classes, methods, and using inheritance

I must admit — some parts, especially functional programming, were quite challenging.

But I understood that it’s okay not to "perfectly" get everything at once.

Practice will make it clearer!

3. Challenges I Faced

  • Functional Programming:

    Lambda expressions and concepts like map() and filter() felt a little abstract.

    I'll revisit these concepts through mini projects.

  • Object-Oriented Programming:

    Understanding self, constructors (__init__), and inheritance was not easy at first,

    but creating small class examples helped me a lot.

4. What's Next?

  • Start working on Mini Projects based on what I learned:
    • Contact Management System
    • RPG Battle Simulator
    • Expense Tracker
    • Encrypted Diary App

I will approach these step-by-step, focusing on solidifying each concept in practice rather than rushing.

5. Final Thoughts

Completing this course wasn't always easy, but it was 100% worth it.

I am proud of myself for pushing through, and I'm excited to keep building on this foundation!

Special thanks to my AI buddy, who supported me like a real coding mentor during this journey!
