OSError when trying to delete keys from redis


I am trying to delete multiple redis keys using scan command.
My code is following
if result:
return_text = "This was pushed to the front end successfully."
# delete cached data in redis
delimiter = config['redis_delimiter']
command = "redis-cli --scan --pattern 'graph_data"+delimiter+str(ds_id)+"*' | xargs redis-cli del"
subprocess.Popen(command)
return return_text
However when line " subprocess.Popen(command)" is getting executed I am getting following error
OSError: [Errno 2] No such file or directory
