numpy is a Python library for scientific computing. Provides a powerful multi-dimensional array object and tools for processing these arrays, which can easily perform numerical calculations, data operations, linear algebra calculations, etc. Numpy's ndarray object can store the same type of data, is more efficient than Python's native list object, and also supports broadcast operations. Numpy also provides many functions for array operations, including mathematical functions, linear algebra functions, random number generation functions, and so on.
