Getting a value from Tkinter OptionMenu in Python

Sure, I'd be happy to help you with that! The OptionMenu widget in Tkinter is used to create a dropdown menu, and getting the selected value from it involves a few steps. Here's a step-by-step tutorial with a code example:
Let's break down the code:
Import the required modules: tkinter and StringVar.
Create the main Tkinter window using tk.Tk().
Create a StringVar variable (variable) to store the selected value from the OptionMenu.
Define a list of options that you want to display in the dropdown menu (options).
Set the default value for the OptionMenu by using the set method on the variable.
Create the OptionMenu widget, passing the root window, the variable, and the options using the *options syntax.
Create a button (get_value_button) that, when clicked, calls the get_selected_value function.
Define the get_selected_value function, which retrieves the selected value from the variable and prints it.
Pack the OptionMenu and the button to display them in the main window.
When you run this script, you'll see a window with a dropdown menu and a button. Select an option from the dropdown, click the button, and you'll see the selected value printed in the console.
