Deleting multiple keys in python-Redis in single command

Question

I have a list of keys, and would like to delete all of them. No pattern matching, nothing, just simple delete. I don't want to run a loop, as there will be around 3-4k keys.

I was trying to pass a list into the delete function, but it didn't work

redis_keys = [key1,key2,key3,key4....keyn]
redis.delete(redis_keys)

In the docs it shows

but not how to pass multiple keys. On SO too all questions are related to deleting while matching keys with pattern, but not with exact keys available.

Answer 1

The *names syntax means that you can pass multiple variables via

redis.delete(*redis_keys)

which is really just a shorthand notation for

redis.delete(redis_keys[0], redis_keys[1], redis_keys[2], ..., redis_keys[-1])

If you know the keys you want to delete, you can combine your lookup with your delete via something like this:

my_key = 'items.per.day.*'
redis.delete(*redis.keys(my_key))
