Using Python to Operate Hazelcast

To use Python to operate Hazelcast database connections and data operations, it is necessary to install the 'Hazelcast Python client' class library. This class library is the official driver between Python and Hazelcast. The following is a complete example code that shows how to use Python to connect to the Hazelcast database and perform insert, query, modify, and delete operations: python from hazelcast import HazelcastClient #Connect to Hazelcast cluster client = HazelcastClient() #Obtain a Hazelcast map map = client.get_map("my_map") #Insert Data map.put("key1", "value1") map.put("key2", "value2") #Query data value1 = map.get("key1") print("Value for key1:", value1) #Modify data map.put("key1", "new_value1") new_value1 = map.get("key1") print("New value for key1:", new_value1) #Delete data map.remove("key2") value2 = map.get("key2") print("Value for key2 after deletion:", value2) #Close Hazelcast client connection client.shutdown() In the example code, we first use the 'HazelcastClient()' function to connect to the Hazelcast cluster. Then, we use 'get'_ The map() function retrieves a Hazelcast map object that corresponds to a distributed map data structure in the Hazelcast cluster. Next, we use the 'put()' function to insert data into the map and use the 'get()' function to query the data. Then, we use the 'put()' function to modify the data and use the 'get()' function again to verify that the data has been modified. Finally, we use the 'remove()' function to delete the specified data and use the 'get()' function again to verify that the data has been deleted. Finally, we use the 'shutdown()' function to close the Hazelcast client connection. It should be noted that the above example is only a basic example of Hazelcast database connection and data operation, and there may be more complex operations and scenarios in practical applications.
