Download NumPy Free Open Source for Windows, Mac & Linux
NumPy is an open source project that aims to enable digital computing using Python. It was established in 2005 based on the initial work of the libraries Numeric and Numarray.
NumPy is always free to use and provided in the generous conditions of the amended BSD License, with 100 percent open source. NumPy was publicly developed by the NumPy consensus on GitHub, and the wider science community of Python.
The role of the NumPy Steering Board is to ensure, working with, and serving the broader NumPy community, the long-term well-being of the project, both technically and as a community. The NumPy Steering Board currently has many members around the world.

What is NumPy?
NumPy is the basic scientific computing module of Python. It is a library of Python that offers a multiDimensional array object, diverse derived objects (for example matrices and masked matrices), and a wide range of methods for fast matrice operations, among them maths, selection, input/output, discrete Fourier transforms linear algebra and basic statistic operations. Random and more simulation.
At the core of the NumPy package is a ndarray object. This encapsulates n-dimensional arrays of homogeneous data types, with many operations performed in the compiled code for performance. There are many major distinctions between NumPy arrays and conventional Python sequences:
✔️ NumPy arrays have a fixed size when created, unlike Python lists (which can grow dynamically). Resizing ndarray will create a new array and delete the original.
✔️ All NumPy array members must be of the same data type to have the same memory size. Exception: you can have object arrays (including Python) that enable arrays of objects of varying sizes.
✔️ NumPy arrays provide sophisticated arithmetic and other sorts of data processing. Such procedures are often carried out more effectively and with less code than with the integrated sequences from Python.
✔️ Many scientific and mathematical packages based on Python use NumPy arrays; Although it usually supports Python sequence input, it converts these inputs to NumPy arrays before processing and often outputs NumPy arrays.
✔️ In other words, for the successful usage of many (or even most) scientific/mathematical programs based on Python, merely understanding how to utilize Python’s built-in sequence types is not enough – one also has to know how to use NumPy arrays.
✔️ Scientific computing has special relevance as regards sequence size and speed. Take the scenario, for example, that each element is multiplied with the appropriate element in a single-dimensional sequence in another sequence of the same length. We can iterate the elements if the data are kept in two Python lists, a and b.
Why NumPy Fast?
Vectorization describes the absence of any explicit looping, indexing, etc., in the code – these things happen, of course, only ‘behind the scenes’ in precompiled, optimized C code. Vector code has many advantages, including:
- Vector code is more concise and easier to read
- Fewer lines of code generally mean fewer errors
- The symbol is very similar to a standard mathematical notation (which makes it easier, usually, to
- notify the mathematical formulas correctly)
The directive results in more ‘Pythonic’ code. Without the directive, the code would be full of ineffective loops and hard to read.
Broadcast is the term used to describe the underlying process behavior of each element; Generally, in NumPy, all operations, not just arithmetic, but logical, bitwise, functional, etc., behave in this implicit manner, i.e. they are broadcast.
Who else uses NumPy?
NumPy fully supports the object-oriented approach, starting with ndarray. For example, ndarray is a class that has many methods and attributes. Many of its methods are reflected by functions in the external NumPy namespace, allowing the programmer to code in any form they prefer.
This flexibility allowed the NumPy array dialect and the NumPy ndarray class to become a de facto language for multidimensional data exchange used in Python.
