The shape indicates the shape of the array, and.The data type or dtype pointer describes the kind of elements that are contained within the array,.The data pointer indicates the memory address of the first byte in the array,.It’s a combination of a memory address, a data type, a shape, and strides: However, you should know that, on a structural level, an array is basically nothing but pointers. The array holds and represents any regular data in a structured way. You see that, in the example above, the data are integers. When you look at the print of a couple of arrays, you could see it as a grid that contains values of the same type:Į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 To work with these arrays, there’s a vast amount of high-level mathematical functions operate on these matrices and arrays. One of these tools is a high-performance multidimensional array object that is a powerful data structure for efficient computation of arrays and matrices. It contains a collection of tools and techniques that can be used to solve on a computer mathematical models of problems in Science and Engineering. In other words, NumPy is a Python library that is the core library for scientific computing in Python. This already gives an idea of what you’re dealing with, right? The library’s name is short for “Numeric Python” or “Numerical Python”. For those of you who are new to the topic, let’s clarify what it exactly is and what it’s good for.Īs the name gives away, a NumPy array is a central data structure of the numpy library. You already read in the introduction that NumPy arrays are a bit like Python lists, but still very much different at the same time.
