I'm using the IDLE command prompt with Python 3.3 and when I enter a multi-line command, I see a blank line rather than the multi-line prompt that has three dots. I know that this is a little thing, but does anyone know how to enable the multi-line prompt?
As others have noted, IDLE will not display the three dots that you are looking for; however, if you must have them, you could always run python from the terminal by typing 'python' into the terminal and pressing ENTER. To exit python from the terminal you could type either 'exit()' or 'quit()' followed by ENTER.
