ruby on rails - How do I check to see if my array includes an object? -

-

I have an array @hors = [] which fills me with some random horses.

How can I check that my @horse array includes a horse which is already present (present)?

I tried to do something like this:

@ suggested_hors = [] @ suggested_hours & lt; & Lt; Horse.find (: First ,: offset => Rand (Horse Quarter)) while @ suggested_horses.length & lt; 8 horses = horses. Search (: first ,: offset = & gt; rand (Horse Cuba)) until @ suggested_horses.exists? (MAR.ID) @ Get Recommended & lt; & Lt; End of the horse end

I also tried to include ? But I noticed that this was only for string. Is present? I get the following error: 

  Undefined method 'exists?' # for; Hey: 0xc11c0b8 & gt;

So the question is how can I check that my array already contains a "horse" so that I can not fill it with the same horse?

Ruby does not have an array exists? Method. And they've got the method to do something like 

  as long as @ suggested_horses.include? (Horse) @ suggested_hours & lt; & Lt; The end of the horse

should work out of the box.

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).
