### py2neo Library Usage and Documentation Py2neo is a client library and toolkit for working with Neo4j from within Python applications. This library provides comprehensive tools that simplify interaction between Python code and the Neo4j graph database. To install `py2neo`, one can utilize pip, which manages software packages for Python: ```bash pip install py2neo ``` For managing different versions of Python alongside multiple project-specific dependencies without conflicts, consider using environment management tools like those mentioned previously[^2]. These allow setting up isolated environments where specific package versions are maintained per-project basis. Once installed, interacting with Neo4j through py2neo involves establishing connections to databases, executing Cypher queries, handling transactions, and more advanced features depending on application requirements. Below demonstrates how to connect to a local instance of Neo4j and run a simple query: ```python from py2neo import Graph graph = Graph("bolt://localhost:7687", auth=("neo4j", "password")) result = graph.run("MATCH (n) RETURN n LIMIT 5").data() print(result) ``` Documentation for detailed guidance on all functionalities provided by this library should be referenced directly via official sources dedicated to maintaining up-to-date information regarding its API and best practices when integrating into projects involving graph data structures managed by Neo4j servers.
