Not just ipython and jupyter. The Python std lib has a module that simulates the built-in interpreter. With a bit of jiggery-pokery, it should be possible to adapt that to allow a symbolic maths DSL. https://docs.python.org/3/library/code.html I think the only limitation is that the code module requires legal Python syntax, so you can't write "2x" to get `2*x`. Nevertheless, it should be capable of exact fractions. The sys module has a display hook for customizing printing: https://docs.python.org/3/library/sys.html#sys.displayhook It would be nice if it had an input hook as well, so that Martin could customise "1/2" to "Fraction(1, 2)". I think that would be a much more useful enhancement than ratiofloat. -- Steve _______________________________________________ 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/XZN27W25VI3A5ZROMNJH7SSANSNDZ2XB/ Code of Conduct: http://python.org/psf/codeofconduct/
