Hi, We have prepared a PEP with our proposal for fine-grained error locations in tracebacks. You can find the PEP here: https://www.python.org/dev/peps/pep-0657/ The discussion is happening in the discourse server: https://discuss.python.org/t/pep-657-include-fine-grained-error-locations-in... To avoid splitting the discussion, *please redirect your comments there* instead of replying to this thread. Thanks! Regards from sunny London, Pablo Galindo Salgado
