[Python] Redis data fetching error, redis.exceptions.ResponseError: WRONGTYPE Operation...

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?
