Unlike some other languages, Python doesn't support getting the mouse 
coordinates directly.

You will have to tell us what version of Python you are using, what 
operating system you are using, and the version of the OS.

If you are using Linux, you probably should tell us what Window Manager 
you have (Gnome, XFCE, KDE, etc...).

Are you using a GUI toolkit, like tkinter, PyQt or similar? If so you 
should tell us.

I'm sorry if this seems complicated, but Python is a language designed to 
operate on hardware where there might not even be a mouse, so it doesn't 
support this function without using an external library, and that will 
depend on your system.
