Description of the Snake Game Program

This program implements a classic Snake game using the Turtle graphics module in Python. The game includes a welcome screen, gameplay mechanics, scoring, and an ending screen when the snake bites itself. Below is a detailed description of the components and functionalities of the program.

Components

1. Welcome Screen:

   • Displays a welcome message and instructions to start the game.
   • The game starts when the player presses the spacebar.

2. Game Setup:

   • The game window is set up with a specific width and height.
   • The background color of the window is set to black.
   • The screen.tracer(0) is used to control manual updates to reduce flickering.

3. Snake and Food:

   • The snake is represented by a series of circles.
   • The food is a red circle that appears at random positions on the screen.
   • The snake moves in a specified direction and grows when it eats the food.
   • The game allows screen wrapping, meaning the snake can move off one edge of the screen and reappear on the opposite edge.

4. Score Display:

   • The score is displayed at the top of the screen.
   • The score increases by 10 points each time the snake eats the food.
   • The update_score function updates the score display without causing flickering.

5. Game Mechanics:

   • The snake moves continuously in the current direction.
   • The player can change the direction of the snake using the arrow keys.
   • The game checks for collisions with itself, which results in the game ending.

6. Ending Screen:

   • Displays a game over message and the player's score when the snake bites itself.
   • Provides instructions to restart the game by pressing the spacebar.

• get_random_food_pos: Returns a random position within the screen boundaries for the food.
• get_distance: Calculates the distance between two points.
• go_up, go_right, go_down, go_left: Functions to change the snake's direction based on user input.
