                                                           y = 100)  
            // this is to finish it
            top.mainloop() 
        
        
        
       // this opens a window saying quit and Open 
        // name of tk
        MyProgram = tk.Tk()
        // frame for the window
        frame = tk.Frame(MyProgram)
        // to make frame work you add this
        frame.pack()
        // a button with quit on it to end the program
        button = tk.Button(frame, 
                           text="QUIT", 
                           fg="red",
                           command=quit)

        button.pack(side=tk.LEFT)

        slogan = tk.Button(frame,
                           text="Open",
                           command=Open)

        slogan.pack(side=tk.LEFT)
        
        MyProgram.mainloop()

If you got this problem try this:-

import tkinter
from tkinter import *
root = tkinter.Tk
root.mainloop()

In your code, you have done:

top=Tk()

You know that Tk() is a class in the __init__ file in tkinter folder(Windows 10, I don't know about mac or linux).

At the top of the code, you have imported tkinter folder as tk. So whenever you want to use a class from it, you will use tk.<widget>.

import tkinter as tk

However, in your code, you just mentioned Tk(). Now, python doesn't know what are you trying to do. In your code, Tk() is neither a function, nor a class. Also, it doesn't know you are referencing it from tkinter folder.

Now that would have been True if you had done a wild-card import or you had imported everything.

from tkinter import *

The fix is:

top=tk.Tk()

Tk is a module of tkinter package, so you have to call it specifying the name of underlying package. Since you've imported tkinter as tk, try replacing:

top = Tk()

with

top = tk.Tk()
