Using Python to Operate Redis

Using Python to operate Redis databases can use the Redis module, which needs to be installed before it can be used. Install the Redis module: pip install redis Connect to the Redis database: python import redis #Establishing a connection r = redis.Redis( Host='localhost ', # Redis server address Port=6379, # Redis server port number Db=0, # database number Password=None, # Redis server password Encoding='utf-8 ', # encoding method ) Data insertion: python #Insert a single key value pair r.set('key', 'value') #Insert multiple key value pairs r.mset({'key1': 'value1', 'key2': 'value2'}) #Batch Insert Multiple Key Value Pairs pipe = r.pipeline() pipe.set('key1', 'value1') pipe.set('key2', 'value2') pipe.execute() Data Query: python #Query the value of a single key value = r.get('key') #Query the values of multiple keys values = r.mget(['key1', 'key2']) Data modification: python #Modify the value of a single key r.set('key', 'new_value') Data deletion: python #Delete a single key value pair r.delete('key') #Delete multiple key value pairs r.delete(['key1', 'key2']) Complete example code: python import redis #Establishing a connection r = redis.Redis( host='localhost', port=6379, db=0, password=None, encoding='utf-8', ) #Insert a single key value pair r.set('key', 'value') #Query the value of a single key value = r.get('key') print(value) #Modify the value of a single key r.set('key', 'new_value') value = r.get('key') print(value) #Delete a single key value pair r.delete('key') value = r.get('key') print(value) The above are the basic operations for operating the Redis database using Python, which can be expanded according to actual needs.
