ModuleNotFoundError: No module named 'tkinter'

The aforementioned error showed up when I tried to use the Turtle class. I was following a tutorial where it's used to pop up a window in the screen. The code is simple:

from turtle import Turtle, Screen
jabba = Turtle()
print(jabba)

my_screen = Screen()
print(my_screen.canvheight)
my_screen.exitonclick()

But in the terminal it says:

ModuleNotFoundError: No module named 'tkinter'

I'm on Ubuntu 20.04 using PyCharm professional IDE.

Solution 1:

Installing python3-tk solved it:

sudo apt-get install python3-tk

Solution 2:

Run this command on terminal

sudo apt-get install python-tk
