Tkinter problem

[Liya Ann Sunny]

I am using Colab. How could  solve this problem.
import tkinter as Tk
from tkinter import *
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='Hello')
# Lay out label
label1.pack()

# Run forever!
master.mainloop()
The error shows that : 
 in ()
  9 
 10 #create main window
---> 11 master = Tk()
 12 master.title("tester")
 13 master.geometry("300x100")

/usr/lib/python3.7/tkinter/__init__.py in __init__(self, screenName, baseName, 
className, useTk, sync, use)
   2021 baseName = baseName + ext
   2022 interactive = 0
-> 2023 self.tk = _tkinter.create(screenName, baseName, className, 
interactive, wantobjects, useTk, sync, use)
   2024 if useTk:
   2025 self._loadtk()

TclError: couldn't connect to display ":0.0"
