如何使用 customtkinter 从标签中删除 CTKLabel？
How would I remove the CTKLabel from a label using customtkinter?
问：
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()
当我在上面运行应用程序时，我会得到一个“CTkLabel”，其中随机名称会消失 如何使该标签永远不会出现？
另外，有没有办法让我的列表完成后，它会重新启动？我添加了销毁函数，因为我不知道这是否可行。任何帮助将不胜感激。

由于选项的默认值是 ，因此如果未给出选项，则会显示该选项。如果您不想显示任何内容，只需设置为覆盖默认值。textCTkLabel"CTkLabel"texttext=""
如果已选择所有名称，要重新启动随机选择，您需要在从以下位置获得随机选择之前清除：chosen_namesnames
...
def button_callback():
# Create a list of names
names = ["Alice", "Bob", "Carol", "Dave", "Eve"]
# Check if all the values in the list have been selected
if len(chosen_names) == len(names):
# clear chosen_names to restart
chosen_names.clear()
# Randomly select a name from the list
name = random.choice(names)
# Check if the name has already been chosen
# or the same as the current one
while name in (chosen_names or [label.cget("text")]):
name = random.choice(names)
# Add the name to the list of chosen names
chosen_names.append(name)
# Update the label text
label.configure(text=name)
label.grid_remove()
...
# set text="" to override the default value "CTkLabel"
label = customtkinter.CTkLabel(app, text="")
...
