Data Science Practice with Python and NumPy

Week 4 in my Data Science Bootcamp at Digital Skola focused on strengthening our Python fundamentals and numerical computing skills. This week, we learned Python data structures, conditional statements, and loops to build logical and efficient programs. We also explored functions, lambda expressions, modules, and packages to write cleaner, reusable, and more structured code. Additionally, we were introduced to NumPy, covering array creation, reshaping, manipulation, slicing, and basic operations—an essential foundation for data analysis and machine learning. 📊 The slides were created collaboratively by my team and me to summarize our Week 4 learning progress.
