NumPy is an open source mathematical and scientific computing library forPythonprogramming tasks. The name NumPy is shorthand forNumerical Python. The NumPy library offers a collection of high-level mathematical functions including support for multi-dimensional arrays, masked arrays and matrices. NumPy al...
x = np.array([_ for _ in range(1000)]) This works, but its performance is hidebound by the time it takes for Python to create a list, and for NumPy to convert that list into an array. By contrast, we can do the same thing far more efficiently inside NumPy itself: x = np.ar...
