Question

For a script that I added on my classroom's TI-84 Plus CE: Python Edition calculators, I'm proud of this script, but help me improve it, please.

Answer 1

Please note that there is no animation included within it, but is a text-based snake game. I'm planning on adding animation later.

```python
# Credits: Aratox
#
# TO PLAY:
#
# - Press the "trace" button
# - 8 - UP
# - 2 - DOWN
# - 4 - LEFT
# - 6 - RIGHT
#
# Good luck!

import random

password = input("Enter the password to play the game: ")
correct_password = "0000"

if password != correct password:
print("Wrong password.")
exit()

snake = [(1, 1)]
food = (5, 5)

UP = (-1, 0)
DOWN = (1, 0)
LEFT = (0, -1)
RIGHT = (0, 1)

direction = RIGHT

def move(snake, direction):
head = snake[-1]
new_head = (head[0] + direction[0], head[1] + direction[1])

if new_head == food:
snake.append(food)
generate_food()
else:
snake.append(new_head)
snake.pop(0)

def generate_food():
global food
food = (random.randint(1, 9), random.randint(1, 9))

while food in snake:
food = (random.randint(1, 9), random.randint(1,9))

def check_collision():
head = snake[-1]
if head[0] < 1 or head[0] > 9 or head[1] < 1 or head[1] > 9:
return True
if len(snake) != len(set(snake)):
return True
return False

def print_board():
for i in range(1, 11):
for j in range(1, 11):
if (i, j) in snake:
print("X", end=" ")
elif (i, j) == food:
print("*", end=" ")
else:
print("." end=" ")
print()

while True:
print_board()

key = input()

if key == "8":
if direction != DOWN:
direction = UP
elif key == "2":
if direction != UP:
direction = DOWN
elif key == "4":
if direction != RIGHT:
direction = LEFT
elif key == "6":
if direction != LEFT:
direction = RIGHT

else:
break

move(snake, direction)

if check_collision():
print("Game Over! Press 5 to restart.")
restart_key = input()
if restart_key == "5":
snake = [(1, 1)]
generate_food()
direction = RIGHT
continue
else:
break
```

Answer 2

I also forgot to mention that typing this on the calculator took me around 2 hours... and this is only 100 lines of code 🫠

Answer 3

you've done a great job on this game, especially considering that you typed it all on a calculator. Keep up the good work!

Answer 4

Your code would fail right off the bat.

```
if password != correct password:
```

Answer 5

... What happened with the embed lol 😨

Answer 6

You likely added an extra `

Answer 7

Also, your code would cause the board to be printed multiple times.

I'd recommend clearing, or removing x amount of lines that are in relation to the board, and re-printing it in the same spot. Gives it an animation effect, of sorts.

Answer 8

If you're going for actual movement of the board, while an input exists, it won't really work.

Answer 9

If you `import os`, you can do the following two clear the console each time, if you'd prefer.

```python
os.system('clear')
```

Answer 10

it hurts my brain

Answer 11

good :)
