c# - Anonymous types query or normal query in LINQ -

- 

  var emps = x in db where x.id = 100 select x; Var emp1 = x1 in db where x1.id = 100 select new {x};

What is the difference between these two questions?

If we use anonymous-types then what performance will increase or what will be the other differences?

There is a big difference between those two questions first, the collection of its entity, the second name is an unknown-type return The collection contains a member called 'x' which contains your unit.

Access to ampses: 

  emps first (). SomeMember

access to emp1: 

  emp1.First (). X.SomeMember

The first path is true and natural, the second is strange and not in my opinion what exactly do you want

Apart from this, it is also not correct That using an anonymous type here will increase the performance, the object represented by the object is in any way, but at this time you are getting it in less favorable form.

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).
