pymgclient is a Memgraph database adapter for Python programming language compliant with the DB-API 2.0 specification described by PEP 249.
mgclient module is the current implementation of the adapter. It is implemented in C as a wrapper around mgclient, the official Memgraph client library. As a C extension, it is only compatible with the CPython implementation of the Python programming language.
pymgclient only works with Python 3.
Check out the documentation if you need help with installation or if you want to build pymgclient for yourself!
Online documentation can be found on GitHub pages.
You can also build a local version of the documentation by running make from
the docs directory. You will need Sphinx
installed in order to do that.
Here is an example of an interactive session showing some of the basic commands:
>>> import mgclient
# Make a connection to the database
>>> conn = mgclient.connect(host='127.0.0.1', port=7687)
# Create a cursor for query execution
>>> cursor = conn.cursor()
# Execute a query
>>> cursor.execute("""
CREATE (n:Person {name: 'John'})-[e:KNOWS]->
(m:Person {name: 'Steve'})
RETURN n, e, m
""")
# Fetch one row of query results
>>> row = cursor.fetchone()
>>> print(row[0])
(:Person {'name': 'John'})
>>> print(row[1])
[:KNOWS]
>>> print(row[2])
(:Person {'name': 'Steve'})
# Make database changes persistent
>>> conn.commit()
