In addition, use partial to send args to a function

from functools import partial
...
## there is no function CharacterSelection in the code you posted
ShotonButton = Button(tk, text="", command=partial(CharacterSelection, 1), bg='red')

when you have time, peruse the Python Style Guide, function names are all_lower_case_with_underscores.
