python - Basic Pygame Program Not Executing -


An animation test was typed into this Python code, I was expecting some errors, but this program only executes

/ P>

> pygame.init ()

to load the phantom image files and later , Sound 

  class processes (object): @staticmethod Def load _image (imagefile): image = pygame.image.load (imagefile) Return image, image.get_rect ()   
 Sprite class  
  class Sprite (Pygame .sprite.Sprite): def __init__ (self): pygame.sprite.Sprite .__ init__ (self) self.image, self.rect = Processes.load_image ('frame1.jpg')   < P> Simple animation function - To make life easier  
  Def animation (self, key_evolution): If key_event == K_DOWN: self.rect.centery = self.rect.centery - 10 Key_event == of_UP: self right. Centry = self.rec T.centery + 10 if key_event == K_RIGHT: self.rect.centerx = self.rect.centerx + 10 if key_event == K_LEFT: self.rect.centerx = self.rect.centerx - 10 return self .   
 Main job:  
  def main (): mecha = sprite () allsprites = pygame.sprite.RenderPlain ((mecha,))   
 Game loop:  
  while correct: page = pygame.display.set_mode ((400, 400)) pygame.display.set_caption ('Animation Test') Pajima .event.get () for events in: if event.type == KEYDOWN: mecha.animation (event.key) if event.Type == QUIT: pygame.quit () sys.exit (0) allsprites.draw ( Page) pygame. Display.update ()   
 Here is the real 'error'  
  C: / Khan's family / Python / daughters versus The zombies / BVJD_Animatext   
 Now this output is:  
  (nothing) C: / Khan family / Python / daughters versus Zombies   
 There is no output, and this is my problem 
 
 
   
 
 
 What do I think when an error occurs? . "You have to click the X button to close it, you will have to spam, and the error will appear in. On this Patialular program, the error is:  
  file" C: / Python 32 / Projects / Delayable Use ", line 45, & lt; module & gt; Allsprites.draw (surface) Name: Error: Name 'allsprites' is not defined   
 That's it.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
