Step 1 − Make sure Python and pip is preinstalled on your system
Type the following commands in command propmt to check is python and pip is installed on your system.
To check Python
python --version
If python is successfully installed, the version of python installed on your system will be displayed.
To check pip
pip -V
The version of pip will be displayed, if it is successfully installed on your system.
Step 2 − Install Tkinter
Tkinter can be installed using pip. The following command is run in the command prompt to install Tkinter.
pip install tk
This command will start downloading and installing packages related to the Tkinter library. Once done, the message of successful installation will be displayed.
# True or False Application in Python using TKinter package.
from tkinter import *
from tkinter import messagebox as mb
main = Tk()
