LINQ to entities - left join with condition -

-

I have a table table game in which FK (by allowing noses) is included in the game table when I do this : 

  Gamewarson [] q = (Select gb from dv.GameVersion.Include ("Game") gv). ToArray ();

This works fine, while playing Game Variable Objects, I can see blank references to the game in some records (just like on the databse), so it's like joining the left Works.

However, when I modify a little query and add a search by the name of the game

gamewarson [] q = (db.GameVersion.Include in GV ("Game ") In which select gv.Game.DisplayName. (" A ") gv). ToArray ();

It behaves like being in a sudden (now does not select zero references) I do not quite understand this behavior. Why is this happening and how can I do a query? I want to apply a game betting game with game game == Null Plus to one of the game columns.

Well if there is no game, then there can not be a display name, so " A "can not be if you want to select the versions of the game also , where there is no game, then you have to do this clearly. Try it: 

  GameWarson [] q = (db.GameVersion.Include from GV ("Game") where gv.Game == faucet || gv.Game.DisplayName.Contains ( "A") Select GV) .Oir ();

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
