food.py

# Our snake should be able to head a piece of food,
#
# which is just going to be a blue circle. And every time it touches the food,
#
# the circle moves to a new, random location on the screen.
#
# If we take a look at our code,
#
# you can see that the main.py controls the entire game.
#
# It dictates how the screen should behave and how the snake behaves.
#
# Now, everything that's to do with a snake,
#
# it's a parent's and behavior, is all captured inside a class.
#
# So everything snake related is inside the snake class.
#
# So what we want to be able to do is to create a new food.py file
#
# and this food.py is going to be its own class.
#
# And the food class is going to know how to render itself as a small circle on
#
# the screen. And then every time the snake touches the food,
#
# then that food is going to move to a new random location.

from turtle import Turtle
import random



# what we want to be able to do is we actually want this class, food, to inherit
#
# from the turtle class.
#
# So that way this food class is going to have all of the capabilities of the
#
# turtle class,
#
# but it's also going to have some specific things that we're going to tell it
#
# how to do so that it behaves like an actual piece of food.
