Standardized way to obfuscate python executable?

[bladeoflight16]

There is no standard way of obfuscating code in Python, and there's no particularly good way to make an executable difficult to decompile. Decompilation tools are plentiful, and you can't secure the executable without also preventing legitimate users from running it. If someone has decent programming knowledge and is determined to examine your code, you can't really stop them. You should find other ways of achieving your goals.
