Because those are outputs of GetWindowText.  For any API that returns a 
string, the Windows API will have you pass in a buffer and a buffer 
size.  In Python, strings can vary in length, so there is no need to 
send a pre-allocated string.  The Python Win32 wrapper conveniently 
creates the buffer for you, and passes the resulting string as a return 
from the function.
