grafeo.Node¶

Represents a graph node.

Properties¶

Property	Type	Description
`id`	`int`	Internal node ID
`labels`	`List[str]`	Node labels

Methods¶

get()¶

Get a property value by key. Returns None if the property does not exist.

def get(self, key: str) -> Optional[Any]

properties()¶

Get all properties as a dictionary.

def properties(self) -> Dict[str, Any]

has_label()¶

Check whether the node has a specific label.

def has_label(self, label: str) -> bool

keys()¶

Return a list of all property key names on this node.

def keys(self) -> list[str]

items()¶

Return a list of (key, value) pairs for all properties.

def items(self) -> list[tuple[str, Any]]

Operators¶

`node["key"]`¶

Access a property by key. Raises KeyError if the property does not exist.

`"key" in node`¶

Check whether the node has a property with the given key.

Example¶

result = db.execute("MATCH (n:Person) RETURN n LIMIT 1")
row = next(iter(result))
node = row['n']

print(f"ID: {node.id}")
print(f"Labels: {node.labels}")
print(f"Name: {node.get('name')}")
print(f"Is a Person: {node.has_label('Person')}")
print(f"All properties: {node.properties()}")

Direct Node Creation¶

# Create node with direct API
node = db.create_node(["Person"], {"name": "Alix", "age": 30})
print(f"Created node with ID: {node.id}")

# Manage labels
db.add_node_label(node.id, "Employee")
db.remove_node_label(node.id, "Contractor")
labels = db.get_node_labels(node.id)
