Excuse me, could you please explain in a step-by-step manner how to create an adjacency matrix in Python? I'm particularly interested in understanding the basics of how to set up the matrix and what libraries or functions are commonly used to accomplish this task. I'm also curious about any potential challenges or nuances that one should be aware of when working with adjacency matrices in Python. Thank you in advance for your insights and guidance.

This process ensures that the adjacency matrix accurately represents the graph's structure, with a 1 indicating a direct connection between two vertices and a 0 indicating no connection.

To represent a graph in Python using an adjacency matrix, we start with a list of tuples that define the edges. Each tuple contains two elements, representing the vertices connected by an edge.

The first step is to initialize an empty matrix of size V×V, where V is the number of vertices in the graph. This matrix is filled with zeros, indicating no direct connection between any two vertices initially.

To construct the adjacency matrix, we iterate through the list of edges. For each edge (u, v), we need to update the matrix to reflect the connection between u and v.

Since the graph is undirected, a connection from u to v implies a connection from v to u as well. Therefore, we set matrix[u][v] = 1 and matrix[v][u] = 1 for each edge (u, v).
