I am using Colab. How could solve this problem.
import tkinter as Tk
If you do this, import 'as tk'.
from tkinter import *
The second import overwrites the first since it imports tkinter.Tk as
'Tk'. Don't try to do both.
import sys
import os
#create main window
master = Tk()
master.title("tester")
master.geometry("300x100")
#make a label for the window
label1 = tkinter.Label(master, text='Hellooooo')
# Lay out label
label1.pack()
# Run forever!
master.mainloop()
The error shows that :
