How can I implement graphs in Python?

You can use libraries like NetworkX or Matplotlib to implement and visualize graphs in Python. Would you like a code example?

Yes, please provide a simple example using NetworkX.

Sure! Here's a basic example:

import networkx as nx
import matplotlib.pyplot as plt

# Create a graph
G = nx.Graph()

# Add nodes and edges
G.add_edges_from([(1, 2), (1, 3), (2, 4)])

# Draw the graph
nx.draw(G, with_labels=True)
plt.show()

This will create a simple graph with nodes and edges. Do you need help with anything else?

How do I add weights to the edges?

You can add weights by using a dictionary when adding edges. For example:

G.add_edge(1, 2, weight=4.2)

This sets the weight of the edge between nodes 1 and 2 to 4.2. Would you like to know how to visualize these weights?
