Review comment (suggestion):
The expression `bytes(345)` creates a bytes object of 345 null bytes (`b'\x00' * 345`), not a bytes object containing the string "345". This is likely unintended. 

If the intention is to use the byte string `b"345"` as a key, the code should be:
```python
r.rpush(b"345", "12", "22", "32", "42", "52")
assert r.lrange(b"345", 0, 0) == [b"12"]
```
```suggestion
        r.rpush(b"345", "12", "22", "32", "42", "52")
        assert r.lrange(b"345", 0, 0) == [b"12"]
```

Code after:
        assert r.lpush("a", "3", "4") == 4
        assert r.lrange("a", 0, -1) == [b"4", b"3", b"2", b"1"]

        assert r.lpushx("a", "4") == 4
        assert r.lrange("a", 0, -1) == [b"4", b"1", b"2", b"3"]
