redis_connstr = redis.apply(
        lambda redis: "{}.<http://redis.cache.windows.net:6380,password={},ssl=True,abortConnect=False%22.format(|redis.cache.windows.net:6380,password={},ssl=True,abortConnect=False".format(>
            BRANCH, redis)
    )

and then I use redis_connstr to assign a value to a dict, and it works, i get a real string as a value in the dict
