fakeredis does not convert keys to strings like redis does

[rancerbeta]

When using a tuple as a key, redis will use the string form of the tuple. Fakeredis returns the key as the original tuple.

Example:
import redis/fakeredis
import time
client = redis.StrictRedis()
client.zadd('test_set', time.time(), (1, 2, 3))
result = client.zrange('test_set', 0, 0)

result returns tuple in array [(1, 2, 3)] in fakeredis, but string in array ['(1, 2, 3)'] in Redis
