Using Python to generate code?

[Tran Tuan Anh]

Many thanks for your comments and advice!

Another concern is that how I can interface Python with Cup/Lex.
Writing parser is a no-joke and tedious to me, hence I would like to
re-use
the existing Cup/Lex scanner and parser. 
Could anyone confirm that it is possible to do so? (I mean naturally
:)

In general, the program I am dealing with needs to manipulate strings
quite a lot. Eventhough we can certainly do with C++, it does not
appeal naturally to me.
