Method 1: OptionMenu

The first method is to use OptionMenu from tkinter . You will have to create a list containing all your desired options. Then you need to have a variable that holds the information regarding which button is currently selected.

Sample code:

from tkinter import *

root = Tk()
root.geometry("300x300")

OPTIONS = [
"Option 1",
"Option 2",
"Option 3"
] #etc

variable = StringVar()
variable.set(OPTIONS[0]) # default value

w = OptionMenu(root, variable, *OPTIONS)
w.pack()

root.mainloop()

Output:

Method 2: Radiobutton

You can use Radiobutton in tkinter to have options.

The arguments that you need to pass in are the window which is root , the text to be displayed in the option button, a shared variable which holds the information regarding which button is currently selected , and unique value to distinguish this radio button.

Note: each radio button should have a different unique value otherwise more than one radio button will get selected.

Parameters to be passed in:

button = Radiobutton(root, text="Name on Button", variable = “shared variable”, value = “values of each button”)
