Broadcasting is the term used to describe the implicit element-by-element behavior of operations; generally speaking, in NumPy all operations, not just arithmetic operations, but logical, bit-wise, functional, etc., behave in this implicit element-by-element fashion, i.e., they broadcast. Moreover, in the example above, aand bcould be ...

operations. Start with a couple one-dimensional arrays. a = np.array([20,30,40,50]) b = np.arange(4) Arithmetic operations applied to arrays in numpy behave element-wise. For adding or subtracting two arrays, this is usually the desired behavior, but for multiplying ar-rays it may not be. Make sure to keep this in mind when performing array ...

Numpy: the basic library that most others depend on, it provides a powerful array type that can represent multidmensional datasets of many di erent kinds and that supports arithmetic operations. Numpy also provides a library of common mathematical functions, basic linear algebra, random number generation and Fast Fourier Transforms.
