Using NumPy for array and matrix math in Python Many mathematical operations, especially in machine learning or data science, involve working with matrixes, or lists of numbers.

In this example, we use the NumPy array’s .shape attribute to obtain its dimensions. We then use range() to iterate through the memoryview with those dimensions as a constraint.
