Using Python to Operate Couchbase

To operate the Couchbase database using Python, you need to use the class library provided by the Couchbase SDK. The following are the steps to operate the Couchbase database using Python: 1. Install the Couchbase SDK: Use pip to install the "Couchbase" class library. You can install using the following command: pip install couchbase 2. Import the required class library: Import the Couchbase class library in Python code. python from couchbase.cluster import Cluster, ClusterOptions from couchbase.cluster import PasswordAuthenticator 3. Create a Couchbase connection: Use the Cluster and ClusterOptions classes to create a Couchbase connection. At the same time, use the PasswordAuthenticator class for authentication. python cluster = Cluster('couchbase://localhost', ClusterOptions(PasswordAuthenticator('username', 'password'))) 4. Open Bucket: Use the Cluster object to open the bucket to be connected. python bucket = cluster.bucket('bucket_name') 5. Obtain Collection Object: Use a Bucket object to obtain a Collection object, which can be used to manipulate data. python collection = bucket.default_collection() 6. Insert Data: Use the Collection object to insert data. You can use the 'insert' method to insert data. python document = {'key': 'value'} collection.insert('document_key', document) 7. Query Data: Use the Collection object to query data. You can use the 'get' method to obtain data. python result = collection.get('document_key') print(result.content) 8. Modify data: Use the Collection object to modify the data. You can use the 'upsert' method to update data. python document = {'key': 'updated_value'} collection.upsert('document_key', document) 9. Delete Data: Use the Collection object to delete data. You can use the 'remove' method to delete data. python collection.remove('document_key') The above is a basic example for connecting to the Couchbase database and performing data insertion, query, modification, and deletion operations. Please note that the ' couchbase://localhost 'and' bucket_ Name 'should be replaced with the actual Couchbase server address and bucket name. Additionally, 'username' and 'password' should be replaced with the actual username and password.
