**### Code Output:**

Inverse Matrix:

[[ 0.6 -0.7]

[-0.2 0.4]]

**### Code Explanation:**

The script focuses on unveiling the mystery behind finding the inverse of a matrix — a common yet intriguing problem in linear algebra and programming. Here’s a step-by-step breakdown of how the magic happens:

**Importing Necessary Library**: The numpy library is imported as`np`

because it’s the Swiss Army knife for matrix manipulation in Python.**Defining the**: This function is the heart of our script. It takes a matrix as input and aims to return its inverse, provided it exists.`find_matrix_inverse`

Function**Validity Checks**: The function begins with sanity checks to ensure the input matrix is square, as finding an inverse is only feasible for square matrices. It raises a`ValueError`

if the matrix isn’t square.**Determinant Calculation**: It calculates the determinant of the input matrix using`np.linalg.det(matrix)`

. The determinant is crucial because if it’s zero, the matrix is singular and doesn’t have an inverse. Again, a`ValueError`

is raised in such cases.**Inverse Calculation**: For the grand finale, if the matrix passes all checks, its inverse is calculated using`np.linalg.inv(matrix)`

. This is where numpy shows its prowess, handling the complex process of inverting a matrix behind the scenes.**Example and Execution**: The script then showcases an example by creating`matrix_example`

, a 2×2 numpy array, and passing it to our function. The calculated inverse is printed to the console.

The script depicts a clear architecture, starting from importing resources, defining a pivotal function with necessary validations, and finally giving a practical example of its usage. It’s designed to handle square matrices and thoughtfully flags errors for matrices that are either not square or singular, ensuring robust operation.
