Different \r behavior is the gist of https://stackoverflow.com/questions/35895864/what-is-the-difference-between-cmd-and-idle-when-using-tqdm.  The new section should have more on the different effect of control characters on different display devices and windows. It should also better differentiate between Python result, which is the string written to stdout, and which is nearly always the same in IDLE and console, and visual display result, which is  outside of Python's control.  This separation is the point of Serhiy's msg246602.
