Verified usage

Verified import paths — ran on the pinned version, not inferred.

ObjectGraph

✓ from objectgraph import ObjectGraph

✗ from objectgraph import Graph

EDGE_TYPE

✓ from objectgraph import EDGE_TYPE

NODE_TYPE

✓ from objectgraph import NODE_TYPE

Create a simple directed graph, add nodes, and display adjacency list.

from objectgraph import Graph, Node # Create a graph g = Graph() # Add nodes node_a = Node('A') node_b = Node('B') g.add_node(node_a) g.add_node(node_b) # Add edge g.add_edge(node_a, node_b) print(g.adjacency()) # Output: {'A': ['B'], 'B': []}

Debug

Known issues

breakingIn v1.0, the import paths changed from submodule to top-level. Code using 'from objectgraph.graph import Graph' will fail.

fix

Use 'from objectgraph import Graph' instead.

affects: >=1.0.0

breakingThe 'adjacency' method now returns a dict with keys as node labels, not Node objects. This change from v0.x might break code expecting Node objects.

fix

Access adjacency by node label string instead of Node instance.

affects: >=1.0.0

deprecatedThe 'add_edge' method previously accepted node objects directly; now it requires Node objects (not strings). Strings may raise TypeError in future.

fix

Always pass Node objects to add_edge.

affects: >=1.0.0

gotchaGraph does not support parallel edges or self-loops. Adding duplicate edges is silently ignored.

fix

Use a multigraph library like NetworkX if parallel edges are needed.
