In good old pascal there was this one-liner command:
repeat until keypressed
Apparently there is no built-in analogue for that in python. I have explored
several different possibilities (pyglet, keyboard, curses, ginput (from
matplotlib) and others) but not managed to find anything that works the way I
want.
In the following example I just want to replace 'waitforbuttonpress' with
something like 'continueuntilbuttonpress' if such a command exists. It could be
a mouseclick or a keystroke from the terminal, for instance 'shift', 'space'
or some character.

### The following two lines should be replaced by

if plt.waitforbuttonpress():
break

draw()
for i in range(20):
plot2.plot([20*(sin(i/10)+1)],[-cos(i/10)],'ro')
pause(0.1)
