Also, if you want to explore this further: (1) Hacking the byte-code is not portable. It won't work in non-CPython implementations, and bytecode is not a stable part of the CPython API either. Hacking the AST may be better. (2) If you must hack the bytecode, there is at least one library for bytecode manipulations out in there, possibly on PyPI. Google for "python byte-code hacking" for more. -- Steve
