6.7.4 Python APIs for Executing CREATE PROPERTY GRAPH Statements
You can create a property graph by executing the CREATE PROPERTY
GRAPH
statement through the Python API.
Creating a Property Graph Using the Python Client
- Launch the Python
client:
./bin/opg4py --base_url https://localhost:7007 --user customer_360
- Define and execute the
CREATE PROPERTY GRAPH
statement as shown:statement = ( "CREATE PROPERTY GRAPH "+ "<graph_name>" + " " + "VERTEX TABLES ( " + "bank_accounts " + "KEY(acct_id) " + "LABEL Account PROPERTIES (acct_id) " + ")" + "EDGE TABLES ( " + "bank_txns " + "KEY (txn_id) " + "SOURCE KEY (from_acct_id) REFERENCES bank_accounts " + "DESTINATION KEY (to_acct_id) REFERENCES bank_accounts " + "LABEL Transfer PROPERTIES(amount) " + ")") >>> session.prepare_pgql(statement).execute()
where <graph_name> is the name of the graph.
The graph gets created and you can verify through theget_graph
method:>>> graph = session.get_graph("<graph_name") >>> graph PgxGraph(name:<graph_variable>, v: 1000, e: 5001, directed: True, memory(Mb): 0)
