Software keyboard

[Mike]

You need to call keybd_event which is (or was in win3.x - win95 at least) in 
USER32.DLL.

Simulate return keypress:
    keybd_event(VK_RETURN,0,0,0);
    keybd_event(VK_RETURN,0,KEYEVENTF_KEYUP,0);

Google turned this up:

Note: This is old stuff -- you'll need to handle different versions of 
windows where that DLL and API are rennamed -- I beleive it is now 
SendInput.

SendMessage and Windows hooks can also work, but not as well in all 
circumstances.

If you feel nervous about programming this, you can probably find/buy a COM 
component that will do this and call it from Python that way.

But, this would seem to fit the bill out-of-the-box:
