💡 Hint

Common Mistakes

Using multi() instead of pipeline() to batch commands

The pipeline() method creates a pipeline object to batch commands. The execute() method executes them all at once.

3fill in blank

hard

Fix the error in the code to execute a Redis transaction.

Redis

pipe = redis_client.multi()
pipe.set('key', 'value')
pipe.get('key')

4fill in blank

hard

Fill both blanks to create a Redis transaction and execute it.

Redis

pipe = redis_client.[1]()
pipe.set('count', 1)
