I am trying to fetch the redis data, then

at first try this script

pool = redis.ConnectionPool(host='localhost', port=6379, db=0)
self.redis = redis.Redis(connection_pool=pool)
for key in self.redis.keys():
    print ("key:",key)

It shows like this,

key: b'asgi:group:347'
key: b'asgi:group:62'
key: b'asgi:group:344'
key: b'asgi:group:305'
key: b'asgi:group:348'

then I try to check ,

print(self.redis.get("asgi:group:348"))

However it shows the error like this, redis.exceptions.ResponseError: WRONGTYPE Operation against a key holding the wrong kind of value

How can I get the value of table?

Redis supports multiple types of values, and you need to know the type of the value in order to fetch it. get() only works if the value is a string.

For a key you know nothing about try calling self.redis.type(key) to find out the type of value stored with the key. You will then need to use the appropriate getter for that type.
