python - List comprehension break down, deconstruction and/or disassemble -


In web2py I am trying to break the understanding of this list, so what I can do with the categories I create it. Any ideas as to break it down? 
  def menu_reck (return) [(x.title, none, url ('store', 'category', args = beautiful_arnal (x.id, x.slug)), Menu_reck (x.children)) or for item X []]   
 In addition to the following which it uses:  
  response.menu = [(Span ('catalog', _ class = 'highlights'), false, '', menu_reck (db (db), selection.) (As_trees ())]]   
 So far I have come with them:  
  def menu_rec (item): for items in x: return x.title, none, URL ('duka I have other variations in it, but every variation is different, Only gives me 1 (a) category, when all categories are given to me than the original.  
 Can anyone see that I'm messing up on this? Any other and all help is appreciated, thanks.   
 
 
 Creates a list by adding an understanding of the list:  
  def Menu_rec (item): results = [] item x or []: url = URL ('shop', 'category', args = pretty_url (x.id, x.slug)) menu = menu_reck (x.children) # Recursive call result. You have added two local variables to break (show x.title, none, url, menu))   
 Show long lines to some extent , And how it will show how it automatically calls back recursively.  
 Your version returned directly to the  for  loop during the first code, and never created a list.
