How do you create multi-dimensional arrays using NumPy?

Create multi-dimensional arrays with NumPy can be achieved through the following steps: 1) Use the numpy.array() function to create an array, such as np.array([[1,2,3],[4,5,6]]) to create a 2D array; 2) Use np.zeros(), np.ones(), np.random.random() and other functions to create an array filled with specific values; 3) Understand the shape and size properties of the array to ensure that the length of the sub-array is consistent and avoid errors; 4) Use the np.reshape() function to change the shape of the array; 5) Pay attention to memory usage to ensure that the code is clear and efficient.

Interface Composition in Go: Building Complex Abstractions

Interface Composition in Go: Building Complex Abstractions

Interface combinations build complex abstractions in Go programming by breaking down functions into small, focused interfaces. 1) Define Reader, Writer and Closer interfaces. 2) Create complex types such as File and NetworkStream by combining these interfaces. 3) Use ProcessData function to show how to handle these combined interfaces. This approach enhances code flexibility, testability, and reusability, but care should be taken to avoid excessive fragmentation and combinatorial complexity.
