I am run into trouble .My code below.But I do not know why there is a char 'b' before output string "Hello Python".

>>> import redis
>>> redisClient = redis.StrictRedis(host='192.168.3.88',port=6379)
>>> redisClient.set('test_redis', 'Hello Python')
True
>>> value = redisClient.get('test_redis')
>>> print(value)
b'Hello Python' //why char 'b' output?

Answer 1

It means it's a byte string

You can use:

redis.StrictRedis(host="localhost", port=6379, charset="utf-8", decode_responses=True)

using decode_responses=True to make a unicode string.
