With Postgresql:

class PostgresContextManager: def enter(self): conn_params = { "host": "127.x.x.1", "port": 5432, "dbname": "test_py", "user": "user", "password": "pass", } self.conn = psycopg2.connect(**conn_params) self.cur = self.conn.cursor() return self.cur

def __exit__(self, exc_type, exc_value, traceback):
    self.cur.close()
    self.conn.commit()
    self.conn.close()

after you can use with PostgresContextManager() as cur: cur.execute("SELECT * FROM x WHERE x= %s", (x.value,)) and you can print or handle the results using row = cur.fetchone() if row is None: print("x not found") else: x = row[0]
