how to sort file in ruby -

-

This is my file content. 

  Receipt = Power Cobre Pabels = Buy Quentos Pargrar ytd .label = Purchase YTD Verification. Error.maxvalue = value is too large, maximum value {0}

I want to sort this content in alphabetical order ... How can I do this? ?

Update: This code will sort my file. 

  new_array = File.readlines ("# {$ base_properties}"). Sort file.open ("# {$ Base_properties}", "w") | File | New_array.each {| N | | File.puts (n)} end

Is there a better way to sort the file?

obvious simplification: 

  new_array = File.readlines ("# {$ Base_properties} "). Sort file. Open ("# {$ base_properties}", "w"). File | File.puts new_array end

I just define a method like this, I'm doing the opposite of the file. Read . It is extremely reusable, and should actually be a part of the standard: 

  def file.write! (Path, content) File.open (path, "w") {| Fh | Fh.write content} end

and then trimmed: 

  file. Write! ($ Base_properties, File.readlines ($ base_properties) .sort)

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).
