__PYTHON_INCLUDED__ = 1

(Although that's probably not what you really mean to do.)

def PYPROC(arg):
	print arg

print "hello python"

--or--

sys.stdout.write("hello python")

Can't be done.  Any sufficiently determined Pythonista can change
anything she wants to.

But, you can do this to keep your edges inside a specific file--

_NOCHANGE = 1

Any variable beginning with an underscore has module-specific scope.

See, there's no real concept of a ``static'' member, or of ``private''
members in Python classes.  All methods and members of all classes are
public.  That's a good thing.

You should investigate the tutorial at http://www.python.org

It's really very good, and with your C++ experience you will have no
trouble at all.
