Similarly, np.empty_like([2, 2], dtype=int, order='C', subok=False) also creates a new array of shape (2,) with data type integer and order C. However, as subok is set to False, it returns a base class array instead of a subclass of the input array. The resulting array has ...
In the above example, we first define a custom data type that consists of three fields -Employee Name(string with length 16), Age (32-bit integer), and Salary (64-bit floating-point number). We then create an empty array with dimensions (2, 3) and data type dt. When we print the ...

3) using np.identity() function. We specify the data type as complex and the diagonal offset as 1. We then multiply the resulting matrix with the complex scalar (1+1j), resulting in a matrix with diagonal elements of 1+1j on the first upper diagonal and 0's elsewhere. ...
