Python 字节的问题

[b"['2018-10-11 08:16:00', 6498, 6525, 6497.5, 6503.5, 1539216960000]", b"['2018-10-11 08:17:00', 6503.5, 6523.5, 6497.5, 6514.5, 1539217020000]", b"['2018-10-11 08:18:00', 6514.5, 6515, 6490.5, 6492, 1539217080000]", b"['2018-10-11 08:19:00', 6492, 6495, 6490, 6490, 1539217140000]",]

我从 redis 取出的数据是这样要怎么将他转换为嵌套列表呢，这个 b 要怎么去掉呢

b 说明是二进制串。转成 unicode 后，按 json 解析。

[json.loads(i.decode().replace("'", '"')) for i in a]

```
>>> d = [b"['2018-10-11 08:16:00', 6498, 6525, 6497.5, 6503.5, 1539216960000]", b"['2018-10-11 08:17:00', 6503.5, 6523.5, 6497.5, 6514.5, 1539217020000]", b"['2018-10-11 08:18:00', 6514.5, 6515, 6490.5, 6492, 1539217080000]", b"['2018-10-11 08:19:00', 6492, 6495, 6490, 6490, 1539217140000]",]

redis 读数据库的时候有个参数是编码成字符串
