Caution: .pyc files can be decompiled to realtively well-structured =
Python code. The dynamicity
of the language (such as access to the local variable table) makes fewer =
optimizations possible
at the bytecode level, so you can get surprisingly straightforward code =
out of a decompilation.

http://depython.net/ is one example of a service that will decompile =
code compiled with Python
2.5 and lower.

I would seriously recommend against treating pyc files as having more =
security than raw .py files.

There are also decompilers for Java bytecode, but their output often =
less closely matches
the input source. Also, the .jars emitted by JRuby will, when decompiled =
by a Java decompiler,
be quite different from the input Ruby code, so you will have some =
obscurity there as well.
