Can you provide a the Python program you requested given the following:
Complete the below
def get_redis_from_config(settings, connection_class=StrictRedis):

    ''''Returns a StrictRedis instance from a dictionary of settings.
    To use redis sentinel, you must specify a dictionary in the configuration file.
    Example of a dictionary with keys without values:
