建立Neo4j链接

!pip install neo4j pyahocorasick numpy pandas --no-warn-script-location

定义数据操作对象

from neo4j_driver import Neo4jConnection, Node

链接并查看节点数量

conn = Neo4jConnection('neo4j://localhost:7687/', 'neo4j', 'Lorne@2022')

conn.create(Node("Person", name="Alice", age=30))
conn.create(Node("Person", name="Bob", age=30))
conn.create(Node("Person", name="Charlie", age=30))

print("数据库中的节点总数：", conn.counts())

创建所有关系

# 创建关系
edges = [('Alice', 'Bob'), ('Alice', 'Charlie')]
conn.relationship('Person', 'Person', edges, 'KNOWS', 'friend')

清空所有的数据

conn.clear()
