Here, we need to define three helper functions for the following purposes:- for displaying the score, for handling the snake and for handling the display of other relevant information in the game respectively.
Next and our last helper function would be to display any sort of message we need to show to the user playing our game.
Also, we will be defining the variables x1_change and y1_change which will be used to denote the changes in the position of the snake based on the input provided by the user.
Also, we need to define the snake_List and snake_length variables to store all the head positions of the snake and the length of the snake respectively.
We also need to initialise the position where the food will spawn in our game each time after it is eaten by the snake.
