A poorly conceived approach for generating randomized attribute combinations given some initial values and weights.

attribute_randomizer.py

""" 
Sources like OpenSea will pull metadata from a contract URI
specified in a e.g. tokenURI function within a contract.
Sample Reference: https://docs.opensea.io/docs/metadata-standards
OpenSea particularly will use values stored within the "attributes"
key, found within a JSON-formatted, to display verifiably-rare
characteristics of an NFT.

Notes:
    This illustrates poor attempts at randomness
