"*** can't assign to operator" error

[OREO Speedwagon]

I'm trying to make a simple version of Robot Finds Kitten as a Pygame project, and currently I'm trying to just draw a diagonal line of "box" items.

Python:

class Robot(pygame.sprite.Sprite):     def __init__(self, image, position):         pygame.sprite.Sprite.__init__(self)         self.src_image = pygame.image.load(image)         self.position = position         self.xinc = self.yinc = 0     def update(self, deltat):         x, y = self.position         x += self.xinc         y += self.yinc         self.position = (x,y)         self.image = self.src_image         self.rect = self.image.get_rect()         self.rect.center = self.position class Box(pygame.sprite.Sprite):     def __init__(self, image, position):         pygame.sprite.Sprite.__init__(self)         self.src_image = pygame.image.load(image)         self.position = position     def update(self, newimage):         x, y = self.position         self.position = (x,y)         self.image = self.src_image         self.rect = self.image.get_rect()         self.rect.center = self.position         if pygame.sprite.collide_rect(robot, self):             self.src_image = pygame.image.load(newimage) rect = screen.get_rect() robot = Robot("Robot.GIF", (0,0)) for i in range(1, 11):     box + i = Box("closed.GIF", (10*i, 10*i))

is the relevant part of my code. The error is occurring in the final line of the sample. It's a popup, which I've never gotten before (although to use pygame we're using 2.5 instead of 3... maybe popups are normal in this version?) and it says "*** can't assign to operator". I'm not changing i, though... just generating a location for my box.

This is because you are trying to assign a value to an expression. I'm guessing you want a list of boxes, which means you would use

code:

box[i] = Box()
