Python offers multiple options for developing a GUI (Graphical User Interface). Out of all the GUI methods, Tkinter is the most commonly used method. It is a standard Python interface to the Tk GUI toolkit shipped with Python. Python with Tkinter is the fastest and easiest way to create GUI applications.

OptionMenu
OptionMenu is an important part of any GUI. It creates a popup menu, and a button to display it. It is similar to the combobox widgets commonly used on Windows.
Syntax:

- Define the datatype of menu text, means integer, string, or any other datatype
- Set initial menu text (That display initially)
- Add menu value in option as a list
