Error reported on Discord with https://github.com/redislabs-training/ru101/blob/main/redisu/ru101/uc03-seat-reservation/seat_reservation.py

Received error when running seat reservation python.

        (_, tier_name, blockname) = block.rsplit(":", 2)
                                       ^^^^^^^^^^^^^^^^^^^^
         TypeError: a bytes-like object is required, not 'str'

Resolved by adding extra line to do the conversion. Tried using Python 3.11 and 3.8. It maybe a python 2 versus 3 difference....

Added a line to do conversion and it works fine.

    block = block.decode("utf-8") 
    (, tier_name, block_name) = block.rsplit(":", 2)

Look into this and adjust as needed.
