Ben Burrill <bburril...@gmail.com> added the comment: The core operators, like multiplication and division, should work for any type that defines the right operators. Hashing is tricky, and reducing the fraction is pretty much off the table. This is why I suggested a superclass. I'll try making a patch sometime soon.
I am aware of sympy and am not proposing that the standard library stray too far into symbolic mathematics. Sympy's re-invention of the fraction makes sense given sympy's scope, but simpler libraries that offer other abstract math features (like one that just implemented a simple Polynomial type) would benefit from using fractions.Fraction. This change would probably make it so that sympy symbols worked with fractions.Fraction, which although unnecessary, might be nice. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31707> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
