It's not very easy to get back to the original source line. f.__code__.co_firstlineno gives the first line number, and other lines must be computed with the help of f.__code__.co_lnotab. Good luck with this one. You may want to look at the "dis" module to see how it is used. -- Amaury Forgeot d'Arc
