python - Why can I not instatiate a new Frame object in Tkinter?

I am trying to make an interactive graph that is displayed in the Tkinter window. However, I am not able to create a Frame object to place in the Grid of the Tkinter window.

I have created my Tkinter object in a class style here is the instantiation of it

window = Tk()
w = Graph(window, size, startX, startY, endX, endY)
window.geometry('1000x1000')
window.title('Tkinter Testing')
window.mainloop()

I am referring to this tutorial: Tkinter Geometry Manager

for x in range(len(self.graph)):
    for y in range(len(self.graph[0])):
        frame = window.Frame(
            master=window,
            relief=window.RAISED,
            borderwidth=1
        )
        frame.grid(row=x,column=y)
        label = window.Label(master = frame, text="testing")

This is the error thrown in the console

Credit goes to @quamarana and @jasonharper for shedding light and explaining the issue.

The answer to this question had to do with how Tkinter is imported. The syntax when instantiating an object is slightly different based on the import statement.

import tkinter as tk or from tkinter import Tk

button = tk.Button(...
frame = tk.Frame(...
label = tk.Label(...

from tkinter import *

button = Button(...
frame = Frame(...
label = Label(...

As @jasonharper pointed out:

If you did from tkinter import *, you would instead have to say Tk() or Label() (this option is generally not recommended, since it's no longer obvious where the definitions of these names are coming from).
