unbound method mainloop() must be called with Tk instance as first argument (got nothing instead)

Question

The below code is a simple code which I tried to check if Tkinter worked...

import Tkinter
top=Tkinter.Tk
top.mainloop()

Acoording to https://www.tutorialspoint.com/python/python_gui_programming.html

this should open a blank window

But the following error message was received

  File "b.py", line 3, in <module>
    top.mainloop()
TypeError: unbound method mainloop() must be called with Tk instance as first argument (got nothing instead)

Any suggestions...

You need to do`top=Tkinter.TK()`. Notice the parenthesis. You use them to create _an instance_ of the `Tk()` OBJECT. — Christian Dean, Jun 30 '17 at 05:53

Tkinter.Tk() creates an instance of Tk() object which act as argument for mainloop. Do this instead:

top = Tkinter.tk() //will open a pop up box
top.mainloop()
