NumPy Library

NumPy, short for Numerical Python, is the fundamental package for scientific computing in Python, providing the foundation for nearly the entire data science ecosystem. Its core feature is the powerful N-dimensional array object (`ndarray`), an efficient data structure for storing and manipulating large, homogeneous datasets. By enabling high-performance mathematical and logical operations on these arrays with syntax that is both powerful and concise, NumPy serves as the essential building block for other key libraries such as Pandas, Matplotlib, and Scikit-learn, making it an indispensable tool for data analysis, machine learning, and complex numerical computations.
