How Can I Correctly Draw Images in Pygame Using `screen.blit()`?

Drawing Images in Pygame: A Comprehensive Guide

Drawing images in Pygame is a fundamental skill for creating visually appealing games and applications. This question covers the common issue of images not displaying correctly when using screen.blit and provides a comprehensive solution.

To draw images using Pygame, follow these steps:

1. Load the image using image.load().
2. Get the image's position and size using get_rect().

To prevent the screen from appearing blank, ensure that you correctly draw the image within your game loop. A typical loop for handling drawing looks like this:

while running:
    # Game code...

    # Draw updates at the start of each frame
    screen.fill(black)
    screen.blit(my_image, my_image_rect)

    # Display the updates
    pygame.display.flip()

Within the loop, we fill the screen with a background color (e.g., black) to erase previous frames. Then, we draw the image using screen.blit(image, rect) with the previously loaded image and its rectangle (rect) indicating its position and size on the screen. Finally, we use display.flip() to display the updated graphics.
