Please use Jupyter Notebooks. Please do all of the assignments to include creating a scrabbe.py file per the instructions. Here is the one that you did before but you forgot to do the scrabble.py. PLEASE CREATE THE SCRABBLE.PY file along this time. Thanks!

There can be a total of **only** two wild cards in any user input (that is, one of each character: one `*` and one `?`). Only use the `*` and `?` as wildcard characters.
