Using Python to Operate Tarantool

To operate the Tarantool database using Python, you need to install the Python driver library Python Tarantool, which is officially provided by Tarantool. You can install it through the following methods: bash pip install python-tarantool Then, you can follow the following steps to connect and operate the Tarantool database: 1. Import necessary class libraries: python from tarantool import Connection 2. Connect to the Tarantool database: python conn = Connection(host='localhost', port=3301) The 'host' and 'port' parameters here specify the host address and port number of the Tarantool database, respectively. 3. Insert data into the Tarantool database: python conn.insert('space_name', (data1, data2, data3)) The 'space' here_ Name 'is the space name in the Tarantool database, and' (data1, data2, data3) 'is the data to be inserted. 4. Query data: python result = conn.select('space_name', index=0, key='key_value') The 'index' here is the index used by the query space, and the 'key' is the key value of the record to be queried. 5. Modify data: python conn.update('space_name', index=0, key='key_value', [('=', field_number, new_value)]) The 'field' here_ Number 'is the field number of the field to be modified,' new '_ Value 'is the new field value. 6. Delete data: python conn.delete('space_name', index=0, key='key_value') The 'index' here is the index used by the query space, and the 'key' is the key value of the record to be deleted. The following is a complete Python code example that demonstrates how to connect and operate a Tarantool database: python from tarantool import Connection #Connect to Tarantool database conn = Connection(host='localhost', port=3301) #Insert Data conn.insert('space_name', (1, 'John', 'Doe')) #Query data result = conn.select('space_name', index=0, key=1) print(result[0]) #Modify data conn.update('space_name', index=0, key=1, [('=', 2, 'Jane')]) #Delete data conn.delete('space_name', index=0, key=1) This example connects to a locally running Tarantool database, inserts a piece of data, queries and prints the data, then modifies the value of the second field of the data, and finally deletes the data. Please note that in practical use, you need to set the correct connection information based on your environment and needs, and set the correct index and field number based on your space structure.
