This is the new code, I am unsure if I made the suggestions the the suggestion intended on my previous post First Python program: Tic-Tac-Toe.
I have only been working on programming for about 3 weeks so anymore suggestions or insight on the original post of the suggestions would be more than welcomed.

'''python 3.7.4'''

os.system('CLS')



# board number setup

board = [0, 1, 2,

         3, 4, 5,

         6, 7, 8]





# Defines the board layout printed to the console

    print(dedent(f'''
