How to go from .sage to .pyc?

[pong]

I have a bunch of old scripts in .sage files. They were compiled into .pyc files years ago.

Unfortunately, I only remember that I ran sage --preparse on the .sage files and got them into .py files but forgot what next.

I tried import py_compile in sage then ran py_compile.compile('xxx.py') which gave me a .pyc file but I couldn't load it or attach it to sage.

I understand one can change the file extension to .spyx and have sage to compile it by loading it into a session but I would like the pyc files by themselves. 

Can I get some help on this?

*.sage files are preparsed by sage preparser, and converted into *.py files.
Conversion into *.pyc files is done automatically, as *.py files are
loaded into Sage's Python interpreter.

One cannot load() or attach() *.pyc files, as far as I know - but why
would you need this?
(unless you want to hide the source of your *.sage scripts from the user)

That's exactly what I want (hiding sources codes from users). 

I'm teaching a class where the students need to implement some algorithms on graphs but I would like to distribute those functions in advance so that they can play with it and see what's the expected output before writing their owns. 

So how can I save those pyc files generated by sage separately and have them run inside a session?
Thanks in advance

I think if you make your *.sage scripts more "pytonic", so that they can be imported by Python "import" statements, then it would suffice to supply *.pyc files only.

Thanks in advance
