Using the standard ctypes library, this should yield the current on screen mouse coordinates without any third party modules:
from ctypes import windll, Structure, c_long, byref
class POINT(Structure):
_fields_ = [("x", c_long), ("y", c_long)]
def queryMousePosition():
pt = POINT()
windll.user32.GetCursorPos(byref(pt))
return { "x": pt.x, "y": pt.y}
pos = queryMousePosition()
print(pos)
I should mention that this code was taken from an example found here So credit goes to Nullege.com for this solution.
