NumPy

NumPy is a Python library for numerical computing that provides powerful n-dimensional arrays and comprehensive mathematical functions. It includes tools for linear algebra, Fourier transforms, and random number generation. Developers use NumPy as a foundational package for scientific computing, data analysis, and array-based operations. The library emphasizes performance through optimized C code while maintaining Python's accessibility and flexibility. NumPy is developed by Charles R. Harris, Eric Wieser, Matti Picus, Pauli Virtanen, and Travis E. Oliphant, and is distributed under the 3-clause BSD License.

NumPy's vectorization, indexing, and broadcasting concepts have become standard approaches in array computing. The library supports a wide range of hardware platforms and computing environments, including Windows, Unix-like systems, and macOS. It interoperates well with distributed computing, GPU, and sparse array libraries. NumPy forms the foundation for a broad ecosystem of scientific and data science packages across domains including machine learning, signal processing, image processing, astronomy, chemistry, and geoscience.
