neo4j批量添加属性

要在Neo4j中批量添加属性,可以使用Python的py2neo库来实现。以下是一个示例代码:
```python
# -*- coding: utf-8 -*-
from py2neo import Graph, NodeMatcher
# 连接Neo4j
url = "http://localhost:7474"
username = "neo4j"
password = "******"
graph = Graph(url, auth=(username, password))
print("neo4j info: {}".format(str(graph)))
# 查询节点
node_matcher = NodeMatcher(graph)
nodes = node_matcher.match('Test')
# 批量添加属性
for node in nodes:
node\["new_property"\] = "new_value"
graph.push(nodes)
```
在这个示例中,我们首先连接到Neo4j图数据库。然后,我们使用NodeMatcher来查询所有的Test节点。接下来,我们使用一个循环来遍历每个节点,并为它们添加一个新的属性。最后,我们使用graph.push()方法将更改保存到数据库中。
请注意,这只是一个示例代码,你需要根据你的实际情况进行修改。确保替换url、username、password和节点的label和属性名称为你自己的值。
