如何擦除标签中的内容？

Question

对不起

所以我正在制作一个座位表，但我似乎无法让它正常工作......再次。每次按下运行按钮时，我都会尝试重置标签，有什么想法吗？

#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()

每次用户按下运行按钮时，我都会尝试重置文本
