Hey guys, i have been working on this for a while and global doesnt seem to be doing anything; help?

Row1 = [" "," "," "]
Row2 = [" "," "," "]
Row3 = [" "," "," "]
Grid = [Row1,Row2,Row3]

x = False

NAC()

[woooee]

Take check() out from under NAC()--capture the return from a function

def check(player):
    if player == Grid[0][0] == Grid[0][1] == Grid[0][2]:
        print("%s wins!", (player))
        return True

Please read the Python Style Guide to make your code readable. Functions and variable names are lower case with underscores.

You have redundant code in the if statements

if YourGo == '7':
    Grid[0][0] = 'X'
elif YourGo == '8':
    Grid[0][1] = 'X' #Player one's turn

DisplayGrid()
check()

Also, you can map the squares to the numbers and use a for loop or simpify like this

if YourGo == '7':
    Grid[0][0] = 'X'
elif YourGo == '8':
    Grid[0][1] = 'X'
elif YourGo == '9':
    Grid[0][2] = 'X'

#------------------------------------
# replace with
this_row ['7', '8', '9']:
if YourGo in this_row:
    row = 0
    col = this_row.index(YourGo)

Grid[row][col] = 'X'

Finally, turn the above into a function and send the player to it so you don't test separately for X and O, i.e. the same code twice.
