actionscript 3 - how to add a needle or arrow from the center of pie chart using action script -

-

There is a pie chart from the center that I need to pull or needle like a needle

Something like this should be done: 

  Var radian: number = Math PI; Var radius: number = 400; Var xpos: Numbers = Math (Radius) * radius; Var ypos: number = mathematics (radians) * radius; Var line: size = new size (); Line.x = stage. Staveway * 0.5; Line.y = Step StageHite * 0.5; AddChild (line); Var g: graphics = line.graphics; G.clear (); G. Line style (2, 0x000000); G. Linto (expose, UPS);

If the degree is required to be converted to radians or radians then you can use it: 

  Degree to radians: (degree * Math. PI) / 180 degrees radius: (radius * 180) / monastery. PI

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).
