如何使用customtinter从标签中删除CTKLabel?

我有这个代码:

import customtkinter
import random

customtkinter.set_appearance_mode("light")

# Create a list to track the names that have already been chosen
chosen_names = []

def button_callback():
    # Create a list of names
    names = ["Alice", "Bob", "Carol", "Dave", "Eve"]

    # Randomly select a name from the list
    name = random.choice(names)

    # Check if the name has already been chosen
    while name in chosen_names:
        name = random.choice(names)

    # Add the name to the list of chosen names
    chosen_names.append(name)

    # Get the label
    label = app.winfo_children()[0]
    # Update the label text
    label.configure(text=name)
    label.grid_remove()

    # Check if all the values in the list have been selected
    if len(chosen_names) == len(names):
        app.destroy()

app = customtkinter.CTk()
app.title("Randomizer")
#replace with image
app.iconbitmap('isologo.ico')
app.geometry("500x500")

# Create a label
label = customtkinter.CTkLabel(app)
label.pack(padx=0, pady=0)

button = customtkinter.CTkButton(app, text="Selector Nombre", command=button_callback)
button.pack(ipadx=20, ipady=20,padx=20, pady=50)

app.mainloop()

当我在顶部运行应用程序时,我会得到一个“CTkLabel”,随机名称会放在那里。我该如何使该标签永远不会出现?

还有,有没有办法在我的列表完成后重新启动?我添加了destroy函数,因为我不知道这是否可能。如有任何帮助,我们将不胜感激。
