import redis

# Connect to the local Redis server
redis_data = redis.Redis(host='localhost', port=6379, db=0)

old_keys = redis_data.keys()
print("All keys in Redis before adding data:")
print(old_keys)

# Add key-value pairs to Redis
redis_data.set("id_1", 123456)
redis_data.set("id_2", 456789)

# Query keys in Redis
print("\nQuery the new keys:")
value_1 = redis_data.get("id_1")
print("id_1: " + str(value_1))
value_2 = redis_data.get("id_2")
print("id_2: " + str(value_2))

new_keys = redis_data.keys()
print("\nAll keys in Redis after adding data:")
print(new_keys)

The output of the program is as follows:

[b'key_2', b'id_1', b'key_1', b'id_2']
