Tkinter: why .grid() method giving an error?

Code:

import tkinter as tk
import random as rd

number = rd.randint(10,51)
trial = 0
chance = 0

window = tk.Tk()
window.title("Guess")
label = tk.Label(window, text="Guess a number that can be anything from '10' to '50', you have 5 chances !!!\n", font=("Arial Bold",20)).pack()

bt = tk.Button(window, text="Enter")
bt.grid(column=3, row=3)

window.geometry('2000x1000')
window.mainloop()

Error: _tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack

If I try to remove .pack() in 'label', the text doesn't load and still the button remains at (0,0) while there is no error

All you have to do is change label to also use grid instead of pack, I changed the line below:

label = tk.Label(window, text="Guess a number that can be anything from '10' to '50', you have 5 chances !!!\n", font=("Arial Bold",20))
label.grid()

The error is quite clear, you cannot mix between pack() and grid() inside a container or window. Here you are using pack() on the label and grid() on the btn. So change label to grid(). Or change bt.grid(..) to bt.pack().

Keep a note, your label is None, it can cause several errors later, if you plan on reusing the label. So the ideal way is to grid()/pack() on next line:

label = tk.Label(window, text="Guess a number that can be anything from '10' to '50', you have 5 chances !!!\n", font=("Arial Bold",20))
label.pack()

And if you don't plan on reusing it, then don't bother giving it a variable name at all.

You need to use either grid or pack, not both. That's what I think from my experience.

Error: _tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack It says it's managed by pack, so you need to use pack manager "OR" grid manager
