I'm not sure that you understand Martin's point: Python doesn't know
anything about pstr1. Imagine that you are doing this in C:

void main()
{
	char * foo = "bar";

	print_var("foo"); /* should print "bar" */
}

How would you implement print_var? 

You couldn't, of course, because print_var has no way of knowing about
the "foo" identifier, just as Python has no way of knowing about the
"pstr1" identifier.

You have to figure out what module you want to add pstr1 to. It's
probably best to create a new module (not __main__) and stick all your
crap in there. You can then use PyModule_AddObject to add pstr1 to that
module.
