$ pip install redis

使用redis：
>>> import redis
>>> pool = redis.ConnectionPool(host='localhost', port=6379, decode_responses=True)   
>>> r = redis.Redis(connection_pool=pool)

使用StrictRedis
>>> pool = redis.ConnectionPool(host='127.0.0.1', port=6379)
>>> r = redis.StrictRedis(connection_pool=pool)
