AttributeError: 'list' object has no attribute 'x' in Python

Question

I'm working on a basic game with python, but the system gives an error

impostors.x = new_x_pos AttributeError: 'list' object has no attribute 'x'

Below is my code, can anyone tell me what I'm doing wrong? I've checked very carefully but still can't find the error, Since I'm a newbie, I don't have much experience so I hope you guys can help me

The problem is the loop for impostors in impostors:. Rename the loop variable to impostor:

def on_mouse_down(pos):
    global impostors, current_level
    for impostor in impostors:
        if impostor.collidepoint(pos):
            if "red" in impostors.image:
                red_impostor_click()
            else:
                handle_game_over()
