Python Data Science with NumPy, Sets, and Dictionaries

To succeed in data science, you must first master how data is organized, stored, and manipulated. Python offers powerful built-in structures like sets and dictionaries, while NumPy provides the high-performance array processing needed for complex calculations. This text-only course guides you from Python beginner to a confident data manipulator. You will start by understanding fundamental computer science concepts, then transition into structuring data with sets and dictionaries, and finally unlock the full power of multi-dimensional NumPy arrays for numerical analysis. What you'll learn: 1. Understand core data organization concepts, including how sets and dictionaries store information. 2. Apply Python type hints to write clean, readable, and maintainable data science code. 3. Create and manipulate multi-dimensional NumPy arrays for efficient numerical computing. 4. Implement vectorization techniques to replace slow loops with fast, optimized operations. 5. Perform mathematical and statistical operations on datasets with confidence. 6. Filter, slice, and reshape complex data structures to prepare them for analysis. The course begins with foundational definitions of object-oriented concepts and basic data structures. You will then progress through written explanations, clear code examples, and practical exercises designed to build your hands-on coding confidence. This course is designed for beginners who want to build a strong foundation in data science, with no prior advanced programming experience required.
