Such as Cheetah?

BTW, you might want to be more specific about your problem at hand. Code
generation is a rarely used technique in Python. Most of the time, it's
more maintainable (and not necessarily harder or more work) to actually
write the code by hand.

print

Seriously, you have to provide more information if you want a meaningful
answer. If the generated code is Python, too, then the advice is most likely
that you don't need to generate any code at all.

Sure, here are some example of self-evaluating python objects, i.e. for each v
below,

v == eval(v)

I'm quite proud of the last one.

v = (lambda x:x%('"''""'+x+'"''""'))("""(lambda x:x%%('"''""'+x+'"''""'))(%s)""")

v = (lambda x:x%('r\"'+x+'\"'))(r"(lambda x:x%%('r\"'+x+'\"'))(%s)")

v = (lambda x:x%`x`)('(lambda x:x%%`x`)(%s)')

v = (lambda x: x+"("+`x`+")")('(lambda x: x+"("+`x`+")")')

v = "\"%s\" %% ((r\"%s\",)*2)" % ((r"\"%s\" %% ((r\"%s\",)*2)",)*2)

And I'm still trying to disembowel it!

v = (lambda x: x+"("+`x`+")")('(lambda x: x+"("+`x`+")")')

v = "\"%s\" %% ((r\"%s\",)*2)" % ((r"\"%s\" %% ((r\"%s\",)*2)",)*2)

If you're proud of the last one, consider moving to Perl. Python is - as
I heard - about elegance and readability of code...

No thanks. It's far too easy to write unreadable code in Perl and I
like a challenge

Seriously - this is a self-evaluating string, not code for landing a
$1bn rocket on Mars. Do you expect it to be readable? I don't.
However, I definitely find a certain elegance to it.
