Embedding python code into text document question.

[Thomas Troeger]

Dear all,

I've written a program that parses a string or file for embedded python 
commands, executes them and fills in the returned value. The input might 
look like this:

process id: $$return os.getpid()$$
current date: $$return time.ctime()$$
superuser: $$
if os.geteuid():
	return "Yes"
else:
	return "No"$$

I've tried several solutions using eval, execfile or compile, but none 
of those would solve my problem. Does anyone have a solution that works? 
Any suggestions? Any help will be appreciated :)

Regards,
Thomas.
