## Classes

Classes form the backbone of **Object-Oriented Programming (OOP)** in Python. Their **integral role** is evident in:

- **Encapsulation:** Classes allow bundling of data and methods that operate on that data within a single unit, ensuring **cohesion and modularity**.
- **Inheritance:** It allows creation of a new class that is based on an existing class, promoting **code reusability** and establishing a relationship between the parent and child class.
- **Polymorphism:** With classes, one interface can be used for a general class of actions, allowing different classes to be treated as instances of the same class through **method overriding**.

In summary, classes provide a blueprint for creating objects and a foundation for OOP, facilitating **structured** and **scalable** code design.

Ready to try your hand at data science? This course is designed to challenge your existing knowledge and hands-on skills, ensuring you are fully prepared for any twists and turns a data science interview might present. We'll push your understanding of critical topics to the limit, assessing your readiness for real-life scenarios.

Let's take a look at what we'll be working with in this course. The first section will acquaint you with Python, a flexible and advanced programming language known for its clear syntax and readability.

NumPy is a fundamental library in Python that facilitates efficient numerical computations with powerful n-dimensional arrays and mathematical functions.

Pandas provides intuitive and versatile data structures for efficient data manipulation and analysis, streamlining the initial stages of the data science pipeline.

Matplotlib is a comprehensive Python library for creating static, animated, and interactive visualizations in Python.


Seaborn is a Python data visualization library based on Matplotlib that provides a high-level interface for creating informative and attractive statistical graphics.

Statistics provides data scientists with foundational techniques and tools to extract meaningful insights from data, allowing them to make informed decisions and predictions based on empirical evidence.

Scikit-learn is an open-source Python library that provides simple and efficient tools for data analysis and modeling, particularly for machine learning. Data scientists use it extensively for its comprehensive collection of algorithms and processing techniques, enabling them to quickly develop and deploy predictive models.
