Python Tkinter not working. Name error

Question

Really simple code, but not working using tkinder in Python.

This code has been copied just as seen in a video tutorial, so I think it could be any config:

from tkinter import*

root=Tk()

miFrame=Frame(root, width=500, height=400)

miFrame=pack()

Label(miFrame, text="Hola alumnos de Python", fg="red", font=("Comic Sans 
MS", 18)).place(x=100, y=200)

root.mainloop()

The error:

Traceback (most recent call last): File "Prueba2.py", line 7, in miFrame=pack() NameError: name 'pack' is not defined

Replace miFrame=pack() with miFrame.pack()

The row miFrame=pack() is an attempt to assign a symbol miFrame to a reference to some known function pack()

In a case, there is no such known to the python interpreter state, it threw an exception mentioned above.

However, the object miFrame, being a row above that assigned to a tkinter.Frame instance, there is an instance-method present - the .pack(), that can be called, instead of an attempt to straight re-assign the miFrame, right after it's instantiation:

miFrame = Frame( root, width  = 500,
                       height = 400
                       )
miFrame.pack() #_____________________ .pack() is a Frame-class instance-method

Label( miFrame, text = "Hola alumnos de Python",
                fg   = "red",
                font = ( "Comic Sans MS", 18 )
                ).place( x = 100,
                         y = 200
                         )
