In this article, you will learn how to create Python GUI for Random Generator. To understand this program, you should have knowledge of the following Python Programming topics:
Problem Definition
Create a python window containing a grid of 2×2 buttons. In that window, place 4 buttons that have 4 different functionalities:
- Button 1: Pressing Button 1 will print a random integer number.
- Button 2: Pressing Button 2 will print a random float number.
- Button 3: Pressing Button 3 will print a random lowercase word containing a-z
- Button 4: Pressing Button 4 will print a random uppercase word containing A-Z
Tkinter Programming
Tkinter is the standard GUI library for Python. Python when combined with Tkinter provides a fast and easy way to create GUI applications. Tkinter provides a powerful object-oriented interface to the Tk GUI toolkit. Creating a GUI application using Tkinter is an easy task.
