Complete the PrintTicTacToe function with parameters horiz_char and vert_char that prints a tic-tac-toe board with the characters as follows.

def print_tic_tac_toe(horiz_char, vert_char): # FIXME: complete function to print game board return 

Ex: print_tic_tac_toe('~', '!') prints:

x ! x ! x ~ ~ ~ ~ ~ x ! x ! x ~ ~ ~ ~ ~ x ! x ! x 

I had problems with whitespacing.
