[Python] Protecting your Python code when doing the deployment

As we know that Python is a scripting language and need interpreter to compile the source code to byte code and execute it. When running python code, the interpreter will read Python file(*.py) and generate compiled Python file(*.pyc) during the first time running or doing the import. Unfortunately, there is no perfect way to protect your Python byte code because there are some tools, like: Python 2.7 decompiler (uncompyle2), can do the reverse engineering.

Here are several tools and approach that can do some kind of protection for your code.

1. Remove the Python source code
> python -m compileall .
or > python -OO -m compileall .
find . -name "*.py" -exec rm -rf {} \;

2. Let Obfuscater help you to obfuscate your code

3. If your python program is stand alone application, I believe PythonInstaller can help you generate an executable file for your Python code.

4. Use Cython
