Includeing Python in text files

[Paolo Pantaleo]

I am working on this:

I have  a text file, containig certain section in the form
<?py
  python code here
py?>

I parse the text file and substitute the python code with its result
[redirecting sys.stdin to a StringIO]. It something like php or
embedded perl.

So my little toy works not bad, but I was wondering if such a feature
already existed, if yes, can you point me out some links?

Thnx
PAolo
