Python reference problem -

-

I am experiencing a very strange problem (for me) in Python.

I have a square menu: (snippet) 

  class menu: "" fixed item "" menu_items = {} letters = map (chr, range (97 , 123)) Diff __int_ (self, menu_items): self.init_menu (menu_items) def init_menu (self, menu_items): i = 0 items in menu_items: self.menu_items [self.characters [i]] = item i + = 1

When I instantate the class, I am in a list of dictionaries, dictionaries are created with this function: 

  def menu_item (Description, verb = none): if action == none: verb = Lambda: Any returns {"description": description, "action": Action}

and then the lists are created like this: 

  t = [Menu_item ("abcd")] m3 = menu.Menu (t) = A = [menu_item ("test")] m2 = menu.Menu (a) b = [menu_item ("update", m2.getAction), menu_item ("Add"), menu_item ("Delete")] m = Menu. Menu (B)

When I run my program, I get the same menu items every time . I have run the program with PDB and as soon as another example of a class is seen, the menu_items of all previous classes are set in the latest list. It seems that the menu_items member is a static member.

What am I seeing here?

menu_itum dict is a class attribute that is all the menu Examples, and instead you should be OK: 

  Category menu: "" defined item "=" character = map (chr, range (97) , 123) shows a menu with the following: Def __init __ (self, menu_items): self.menu_items = {} self.init_menu (menu_items) [...]

Take a look for more thorough discussion in between class attributes and frequency attributes.

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
