same on Windows, but it often appears *beneath* the window you're typing 
into, so you have to look for it in the task bar.

this also relies on Python being able to keep the Tkinter event loop 
going behind the scenes; different command-line implementations have 
different limitations.

for example, on Windows, the event loop runs only when you're at an 
empty Python prompt; as soon as you start typing the next command, the 
interpreter switches over to "text input mode", and the event loop is 
paused until you press return.
