NumPy

NumPy is the fundamental Python package for high-performance scientific computing, centered on the powerful N-dimensional array object (ndarray).

NumPy (Numerical Python) is the foundational library for scientific computing in Python, providing the core `ndarray` (N-dimensional array) object . This object is a homogeneous, fixed-size container that enables highly efficient, vectorized operations: often up to 50x faster than standard Python lists for large datasets . The library includes a comprehensive collection of routines for fast array manipulation, including linear algebra, Fourier transforms, and random simulation . Its performance advantage stems from its core being optimized C and C++ code , establishing it as the universal data structure for data exchange across the entire Python scientific computing ecosystem.
