To make a ball throwing game

Traceback (most recent call last):
  File "c:\Users\Jeongyoon\Desktop\pythonwork\l\pypang.py", line 96, in <module>
    ball_size = ball_images[ball_img_idx].get_rect().size     
AttributeError: 'str' object has no attribute 'get_rect'

I keep getting errors like this, But I don't know how to solve it. Help me

ball_images list variable is assigned 'file path and filename' as str type.

The str type does not have the get_rect() method. Image should be pygame.image.load to make it ImageFileObect.

You've already loaded all the other image files, but you made a mistake there

I think you should also check this part in screen.blit below.
