I have this code for a maze but I want to modify it by showing some statistics at the end of the game

import random

from typing import List, Tuple, Optional

def make_grid(w: int, h: int, player_coord: Tuple[int, int],

gold_coord: Tuple[int, int]) -> List[List[str]]:

grid = [['(_)' for i in range(w)] for j in range(h)]

x, y = player_coord

grid[y][x] = '(x)'

x, y = gold_coord

grid[y][x] = '(o)'

return grid

def print_grid(grid: List[List[str]]) -> None:

s = ''

for row in range(len(grid)):

s += ''.join(element for element in grid[row]) + " "

print(s)

def update_grid(grid: List[List[str]], w: int, h: int, px: int, py: int,

dx: int, dy: int) -> Optional[Tuple[int, int]]:

if (px + dx < 0) or (px + dx >= w) or (py + dy < 0) or (py + dy >= h):

return None

grid[py][px] = '(_)'

grid[py+dy][px+dx] = '(x)'

return (px+dx, py+dy)

def get_moves(d: str) -> Tuple[int, int]:

if d == "N":

return 0, -1

elif d == "S":

return 0, 1

elif d == "E":

return 1, 0

else:

return -1, 0

def get_direction() -> str:

d = input("Which way would you like to move? Choose N, S, E, W. ")

while (len(d) != 1) or (d.upper() not in 'NSEW'):

d = input("Invalid input. Choose N, S, E, W. ")

return d.upper()

# ==== Finish the functions above according to their docstrings ==== #

# ==== The program starts here. ==== #

# ==== Do NOT change anything below this line. ==== #

if __name__ == "__main__":

w = int(input("Width: "))

h = int(input("Height: "))

p_x = p_y = 0

gold_x = random.randint(1, w - 1)

gold_y = random.randint(1, h - 1)

game_won = False

grid = make_grid(w, h, (p_x, p_y), (gold_x, gold_y))

while not game_won:

print_grid(grid)

d = get_direction()

# the following line unpacks the tuple returned by get_moves

# this means the first element in the returned tuple gets assigned

# to dx, the second element in the tuple assigned to dy

dx, dy = get_moves(d)

new_xy = update_grid(grid, w, h, p_x, p_y, dx, dy)

if new_xy:

p_x, p_y = new_xy

game_won = (p_x == gold_x) and (p_y == gold_y)

print("Congratulations! You won.")
