The `eval(repr(x)) == x` is not a segment of my code; rather it is part of Python's description of what 'repr' should do:
https://docs.python.org/3.4/library/functions.html?highlight=repr#repr Specifically: ` For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval()` <https://docs.python.org/3.4/library/functions.html?highlight=repr#eval> So everyone in this thread can stop mentioning security concerns; I'm sure we're all aware of those and we should instead focus on what repr should do and shouldn't do. I think it's weird to not fulfill this promise, when it should be easy to do. Further, I agree that 'inf' is: 1. Too backwards incompatible 2. Not the right format for Python (Python likes pascalcase, like `None`, `True`, `False`) So again, I'd like to not focus on arguing whether a particular codebase should be using 'eval' on strings generated by repr. Rather, my point was that the current behavior does not follow what Python suggests and says 'repr' should do. ---- *Cade Brown* Research Assistant @ ICL (Innovative Computing Laboratory) Personal Email: brown.c...@gmail.com ICL/College Email: c...@utk.edu On Fri, Sep 4, 2020 at 9:31 PM Greg Ewing <greg.ew...@canterbury.ac.nz> wrote: > On 5/09/20 10:51 am, Chris Angelico wrote: > > If you make "inf" a keyword, then even the Python > > standard library is broken. > > The OP didn't suggest that, he suggested adding a new name > such as Infinity that reprs could use. > > -- > Greg > _______________________________________________ > Python-ideas mailing list -- python-ideas@python.org > To unsubscribe send an email to python-ideas-le...@python.org > https://mail.python.org/mailman3/lists/python-ideas.python.org/ > Message archived at > https://mail.python.org/archives/list/python-ideas@python.org/message/TTFTEBD437MK4BCVET7SGUEVJYS6ZET6/ > Code of Conduct: http://python.org/psf/codeofconduct/ >
