Python-redis keys() returns list of bytes objects instead of strings

I'm using the regular redis package in order to connect my Python code to my Redis server.

As part of my code I check if a string object is existed in my Redis server keys.

string = 'abcde'
if string in redis.keys():
  do something..

For some reasons, redis.keys() returns a list with bytes objects, such as [b'abcde'], while my string is, of course, a str object.

I already tried to set charset, encoding and decode_responses in my redis generator, but it did not help.

My goal is to insert the data as string ahead, and not iterate over the keys list and change each element to str() while checking it.

Thanks ahead

One solution can be:

decode the redis key 

print(key)
#output is : b'some_key'

print(key.decode())
#output is : 'some_key'

Updated :

Pass dictionary object into RedisPost class then decoding individual item and storing them as a object. 

class RedisPost():
   def __init__(self, dic):
      for k,v in dic.items():
          if not isinstance(k,int):
             var = k.decode()
             setattr(self,var,v.decode())


my_dic = {'a':12, 'b':123}
obj = RedisPost(my_dic)
print(obj.a) # output will be 12

Previous answers are correct in that the decode_responses connection parameter is needed to do this automatically, what they omit is that this needs to be set on the ConnectionPool instead if the connections are made using the pool. The below snippet will set the 'decode_responses' value on all clients to true, even if the client sets itself to False during connection

pool = redis.ConnectionPool(host=REDIS_HOST, port=REDIS_PORT, db=REDIS_DB, password=REDIS_PWD, decode_responses=True)
