This is because the command actually forks out and while the input comes through to the current terminal, it's owned by a completely different parent (that remains alive after you ...

Here's the two ways I'd go with. Firstly, not running it from a terminal; hit Alt+F2 to open the run dialog, and run it from there (without &). From a terminal, run nm-applet & But do NOT close the terminal yourself. That is, do not hit the X-button to close, and do not use File -> Exit from its menubar.

You can turn ...

Though a proper library is the best solution, I'd like to show a simple alternative: use \r (carriage return) instead of \n (line feed) for line endings, so that that the cursor is placed at the start of the current line, instead of on the next line. #! /usr/bin/python3 from time import sleep for i in range(100): print('[' + '='*i + ' '*(100-i) + ']', ...
