High Quality Content by WIKIPEDIA articles! NumPy is an extension to the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large library of high-level mathematical functions to operate on these arrays. The ancestor of NumPy, Numeric, was originally created by Jim Hugunin. NumPy is open source and has many contributors. Since the standard Python implementation is an interpreter, mathematical algorithms often run much slower than compiled equivalents, such as those written in C. NumPy addresses this problem for many numerical algorithms by providing multidimensional arrays and lots of functions and operators that operate on arrays. Thus any algorithm that can be expressed primarily as operations on arrays and matrices can run almost as fast as the equivalent C code.
