------------------------------------ Project Description ------------------------------------

This Python tutorial we will see how to Create an animated dark night sky scene using the Tkinter library.
The animation includes a static moon and moving stars.

What We Will Use To Build This Project ? :
- Python Programming Language.
- Tkinter Library (To Create The Gui).
- Visual Studio Code Editor.

What We Will Do In This Project ? :

Class Definition:
- DarkNightSky: A subclass of tk.Canvas that represents the night sky with stars.
- Moon: A separate class responsible for drawing the moon on the canvas.

Constants:
- Frame dimensions (frame_width, frame_height).
- Number of stars (num_stars).
- Star size (star_size).
- Animation delay (animation_delay).

Initialization:
- Initializes the canvas size and background color.
- Generates random coordinates for stars.
- Creates an instance of the Moon class.

Star Generation:
- Randomly generates star positions within the canvas.

Star Animation:
- Moves stars to the right and down in each frame.
- Resets stars' positions if they move beyond the frame boundaries.
- Continuously schedules the next frame for the animation.

Drawing the Scene:
- Clears the canvas.
- Draws the dark night background.
- Draws each star as a small white rectangle.
- Draws the moon as a white oval.

Moon Class:
- Contains constants for moon size and position.
- Draws the moon on the provided canvas.
