Write the Python code for:

Example:

=====>

def compute_PCA): compute the transition matrix P from addjacency matrix A. PE30i] represents the probability of moving from node i to node j Input: A: adjacency matrix, a (n by n) numpy matrix of binary values. If there is a link from node i to node j, ALj]0i] -1. Otherwise AL3Cij-0 if there is no link P: transition matrix, a (n by n) numpy matrix of float values.PIi]i] represents the probability of moving from node i to node Output: The values in each column of matrix P should sum to 1 ## INSERT YOUR CODE HERE return P
