This is a really good point. I think a screen reader that reads out whitespace would be really annoying if it were more frequent than, say, paragraph breaks. > However, the existing `/` was given a backwards incompatible meaning of > "true division" and the new `//` operator took on floor division.

But by freshman year in college students expect real division (either with a fractional result or a float result). I think it was better to cater to that prejudice. (At least that's true here in Japan, where few students do programming before they get here, and was true in Columbus Ohio a couple decades ago. These are schools where most students come from pretty good high schools and the students have access to computers to learn programming if they wanted to.) _______________________________________________ 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/TCG5DKNAB3BAJG563IIG6FR5DBZ5ABQL/ Code of Conduct: http://python.org/psf/codeofconduct/
