Some days ago I found a very easy pythonic way to show a VBA-like MessageBox. It was created with only one line of cpython code.
The code is very very easy. Simply change the last integer parameter to change the style of the message box.
msgbox = ctypes.windll.user32.MessageBoxA
ret = msgbox(None, 'Press OK to end the demo.', 'Deviare Python Demo', 0)
