This is known, has been discussed on previous issues (can't find numbers now), and is not a bug. Your code outputs a stream of 21 characters to 'file' sys.stdout, which for code executed by IDLE is, by default, directed to Shell. The effect of outputting Ascii control characters to a display device depends on the device. On a hard-copy printing terminal, the source from which \r in particular was taken, the effect of your code would be the 10 digits printed on top of each other. In an edit box on a screen, such as this Comment box on Firefox, characters are normally just inserted as received. If I type 0, Left, 1, Left, ...., 9, the result is '9876543210'. The current intended Shell behavior is what you see -- display (or not) chars as received. Changes have been rejected in the past but I am considering adding a 'terminal' mode. ---------- resolution: -> duplicate stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40591> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
