how to create identity matrix in python using numpy

Here's a step-by-step tutorial on how to create an identity matrix in Python using NumPy, along with a code example:
If you haven't installed NumPy yet, you can do so using the following command:
In this example, we've created a 3x3 identity matrix, but you can adjust the matrix_size variable to create identity matrices of different sizes.
The resulting identity_matrix will be a NumPy array representing the identity matrix of the specified size. The diagonal elements will be 1, and the off-diagonal elements will be 0.
That's it! You have successfully created an identity matrix in Python using NumPy. Adjust the matrix_size variable to create identity matrices of different sizes as needed.
