You don't have to look that far. Jython compiles Python code into Java
bytecode; IronPython compiles Python code into Microsoft intermediate
language.

The easiest way to create a .pyc file is to create a Python file,
and then compile that. There are various tools that compile X to
.pyc. For example, Fnorb compiles OMG IDL into .pyc files.

That's correct.

There is the dis module and its documentation. However, as I said, in
Python, you don't really *need* to create .pyc files directly, as
the Python compiler is always available through the compile() builtin
function. This is unlike Java or .NET, where the compiler is not
available in the JRE, or the .NET commercial framework.
