tudent question python, python code, please help me fix the error

CODE:

import copy import random import pandas as pd import time import matplotlib.pyplot as plt import sys

INF = 99999999

def random_graph(num_vertices, max_cost): cm = [[0] * num_vertices for i in range(num_vertices)] for i in range(num_vertices): for j in range(num_vertices): if i == j: cm[i][j] = INF else: cm[i][j] = random.randint(1, max_cost) return cm

def init_dist(matrix): dist = copy.deepcopy(matrix) n = len(dist) for i in range(n): dist[i][i] = 0 return dist

def to_table(matrix): n = len(matrix) table = [[] for i in range(n)] for i in range(n): for j in range(n): if matrix[i][j]

def get_edges(matrix): edges = [] n = len(matrix) for i in range(n): for j in range(n):
