<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edges [(0, 1), (2, 3)], after adding a new vertex using g.add_vertex(), can you check if the VertexCollection 'stale' status is True using the g.vs object?
### Response:
import igraph as ig

# Create a graph
g = ig.Graph([(0, 1), (2, 3)])

# Add a new vertex, making the vertex collection 'stale'
g.add_vertex()

def check_stale_status(vertex_collection):
    try:
        # Try to access the VertexCollection's attributes
        print('First vertex:', vertex_collection[0])
        print('Stale status:', vertex_collection.stale)
    except AttributeError as e:
        print('Caught exception:', e)

# Check VertexCollection 'stale' status
check_stale_status(g.vs)
