Как я могу удалить содержимое в ярлыке?

Question

Извините за беспорядок

поэтому я делаю сидения, и я не могу заставить его работать правильно ... снова. Я пытаюсь сделать сброс метки каждый раз, когда я нажимаю кнопку запуска, любые идеи?

#commands: add name , Run 

#imports 
import random 
from time import sleep 
from tkinter import * 

#Console and background Handlers 
Tables = 6 
Names = [] 

def AddNames(): 
    NewNames = e.get("1.0", 'end -1c') 
    if NewNames in Names: 
     print("Name Already exists") 
    elif NewNames == "": 
     print("Empty") 
    else: 
     Names.append(NewNames) 
    print(Names) 
    e.delete(1.0, END) 

def Random(): 
    RandomNum = random.randrange(Tables) 
    if RandomNum == 0: 
     RandomNum = random.randrange(Tables) 
    return RandomNum 

def run(): 
    X = 0 
    for i in Names: 
     #print(Names[X]) 
     print("Table: " + str(Random())) 
     X += 1 
#text = Label(popup, text = "") 
     text = Label(popup, text= Names[X] + "\n" + "Table: " +  str(Random())) 
     text.pack() 

#GUI Handler 
root = Tk() 
root.geometry("1024x768") 

e = Text(root, bd = 10, font=("Comic Sans MS", 50) ,width = 15, height = 2) 
e.pack() 

popup = Toplevel() 
popup.title("Seating Chart") 

AddNameButton = Button(root, text = ("Add Name"), width = 15, height = 5,  command = AddNames) 
AddNameButton.pack() 

RunButton = Button(root, text = ("Run"), width = 15, height = 5, command = run) 
RunButton.pack() 



root.mainloop() 

Я пытаюсь сбросить тексту каждый раз, когда пользователь нажимает кнопку запуска
