Can't pass a bytearray to SET

Version: redis-py 3.3.8 and redis 5.0.5

Platform: Python 3.6.8 on Ubuntu 18.04

Description: Redis strings are should be binary safe, but redis.set(key, value) doesn’t accept a bytearray as a valid type. Passing a bytearray in as a value, results in the following exception: Invalid input of type: 'bytearray'. Convert to a byte, string or number first.

I understand that this might be a limitation of Python or perhaps I’ve misunderstood the Redis documentation. Thanks in advance.

Example code:

#!/usr/bin/python3
import redis

redis = redis.Redis(host="localhost", port=6379, db=0)

# This will result in an exception
redis.set("my-key", bytearray(10))

All keys and values need to be serialized to bytes before being transmitted to the Redis server. redis-py only knows how to implicitly convert the following types: bytes, str, float and int.

You can convert the bytearray to bytes yourself with: redis.set('my-key', bytes(bytearray(10)))

Improved the error message to be more obvious.
