Python Animation - Text Falling Down

Key Animation Concepts

• Individual Objects: Standard Label widgets cannot move fluidly; using canvas.create_text allows for pixel-perfect positioning.
• Staggered Start: Each character is assigned a delay value that decreases each frame, ensuring they don't all fall at once.
• The .after() Loop: This is the standard way to create animations in Tkinter without freezing the main application window
