How to get name of button when clicked - tkinter python

Question

I am trying to get the name of a button when pressed. I have looked at several other answers, but I don't understand how to get them to work. This is what I have:

number = 0
location = 0
characters = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']
text_list = []
for idx in characters:
    text_list.append(Button(window, text=characters[number], command = clear))
    text_list[-1].place(x=location, y=0)
    location += 18
    number += 1

it makes a button for every letter in the alphabet (I am making hang man). The unstyled result looks like this:

I now want a way to get the name of the button, so that I know what letter was pressed. That is what I need help on.

Try using:

import tkinter as tk
import string # string.ascii_lowercase = "abcdefghijklmnopqrstuvwxyz"


def button_pressed(button):
    # `button.cget("text")` gets text attribute of the button
    print("Button text =", button.cget("text"))


text_list = []
window = tk.Tk()

# Iterate over each letter in the alphabet
for character in string.ascii_lowercase:
    # Create the button
    button = tk.Button(window, text=character)
    # Add the command attribute to the button
    button.config(command=lambda button=button: button_pressed(button))
    # Show the button on the screen using `.pack` because it's much easier to use
    button.pack(side="left")
    # Append it to the list of buttons
    text_list.append(button)

window.mainloop()

It passes the button to the function which uses button.cget("text") to get the text from the button.

just pass the name you want to get from callback

from tkinter import *
for idx in characters:
    button = Button(name=characters[idx], command=lambda name=characters[idx]:print(name))
    # pack, grid, place
