Images don't load while javascript while loop runs -

-

I am writing an image preloader for my html5 project and I've hit a problem. Images used in the game are defined in javascript with the object of the image such as: 

  images = new array (); Images [0] = new image (); Images [0] .src = '/images/tiles/grass.png';

As soon as the "document.ready" pre-loader function is run as shown below. 

  function preloader () {while (loaded! = Images.length) {var loaded = 0; For {Var loadTest = 0; loadtest

The problem is that the loop never ends because the images [loadTest] I have tested this page to run a function after loading, when the image is unnecessary and it works just fine.

For this reason I am convinced that while the loop is running, the images are stopping loading. If it is true how will I go about fixing this problem?

Optionally for a lifting event that you can load images or a setTimeout or set interlabel Voting through the call. This makes the code run in non-intercept fashion. 

  setInterval ('checkimages ()', 1000)

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).
