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='Hellooooo')
# Lay out label
label1.pack()

# Run forever!
master.mainloop()
The error shows that :
<ipython-input-17-a60049376d65> in <module>()
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()

You're either not running an X server, or having problems to connect to it.

Are you sure that Google Colab supports X11 at all? This link doesn't
seem to support that idea:

What's the point? That has no relation to the question.

"import A as B" does not define A. That's a feature, not a bug.

No, it's not. It's only because this line triggers my response:-)

You have posted this as an answer to Liya's question about Google Colab.
What you wrote has nothing to do with it and does not help with Liya's
problem.

I guess you wanted to post another question? Then please open a new
thread. In addition, the question is unclear, you just posted a
transcript of three lines of Python.

I posted to point out there is an error in Liya's script. It's not related to Colab, but it may relate to his problem.

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.

Ah! Now I get it, sorry, missed that earlier.
