Question

Почему мой код не выдаёт рандомное название в Tkinter(Python) from tkinter import *
import random
import sys
root = Tk()
root.title("Приложение для начинающих")
root.geometry("800x600")
root["bg"] = "thistle1"

("Dokkaebi")]
length_code_list1 = len(code_list1)

code_list2 = [("Smoke"),("Mute"),("Castle"),("Pulse"),("Doc"),("Rook"),
("Tachanka"),("Jager"),("Bandit"),("Frost"),("Valkyrie"),
("Echo"),("Mira"),("Ela"),("Lesion"),("Vigil"),("Caveira"),

length_code_list2 = len(code_list2)
