c# - is it better practice to return a complex object or use reference/out parameters? -

-

I am putting a method that is considered to evaluate the input and if all conditions are found or false Some true test fails, if there is a failure, then I also have some kind of position message available for the caller.

The designs I have come up include the returning of bool and using an out (or ref) parameter for the message, an example of a (specially designed) class bool And returning with string properties or even returning an NM or returning signal or a specific error is returning. What is the best way to get all information from the method? Is any of these "good"? Do anybody have other recommendations?

I usually try to return a complex object and an out parameter when I have to do < / P>

But you see the TryParse methods in NET's conversions, and they follow the pattern of returning a value of the converted values ​​and an external parameter return. Therefore, I do not think it is bad to get the parameter out - it really depends on you what you are trying to do.

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).
