I use redis in python. I try to insert file names into redis. Here's how I do it:

onlyfiles = [f for f in os.listdir(".") 
  if f.endswith('.txt') and os.path.isfile(os.path.join(".", f))]
for x in onlyfiles:
   r.rpush('filename', x)

My code failed in r.rpush(). The error as below:

redis.exceptions.ResponseError: WRONGTYPE Operation against a key holding the wrong kind of value

How can I insert the file name correctly?

Have you verified that the key `filename` is a list? `TYPE filename` – Klaus D. Feb 28 '19 at 08:19
filename is a string. I want to create list with 'filename' as key. – roscoe_x Feb 28 '19 at 08:25
I mean **on REDIS*. What is the type in REDIS? – Klaus D. Feb 28 '19 at 08:29
the type of filename is "none" – roscoe_x Feb 28 '19 at 08:35

The error you are getting signifies that the command is being run against a key that holds the wrong type. `RPUSH` would create a new list with the elements specified if the key did not exist. – TheDude Feb 28 '19 at 15:55
