You probably need to install it using something similar to the following:
-
For Ubuntu or other distros with Apt:
sudo apt-get install python3-tk
-
For Fedora:
sudo dnf install python3-tkinter
You can also mention a Python version number like this:
-
sudo apt-get install python3.7-tk
-
sudo dnf install python3-tkinter-3.6.6-1.fc28.x86_64
Finally, import tkinter
(for Python 3) or Tkinter
(for Python 2), or choose at runtime based on the version number of the Python interpreter (for compatibility with both):
import sys
if sys.version_info[0] == 3:
import tkinter as tk
else:
import Tkinter as tk
