Question

I am trying to find out values stored in a list of keys which match a pattern from redis. I tried using SCAN so that later on i can use MGET to get

Reminder this is a trivial task if you're using the scan_iter method on the redis python library:

from redis import StrictRedis

redis = StrictRedis.from_url(REDIS_URI)

keys = []
for key in redis.scan_iter('foo:bar:*', 1000):
    keys.append(key)

In the end, keys will contain all the keys you would get by applying @khanou 's method.

This is also more efficient than doing shell scripts, since those spawn a new client on each iteration of the loop.
