python tkinter Combobox不会填充Windows硬盘驱动器

Question

亲爱的人们，我的python Combobox没有填充Windows驱动器。 请帮忙！！！

import tkinter as tk
from tkinter import ttk
from tkinter import font
import os.path

win = tk.Tk()
win.title("AR Duplicate File Search")
win.geometry("600x600")
win.configure(bg = 'green')


#----------------------------------Combo Box----------------------------- 
dl = ['ABCDEFGHIJKLMNOPQRSTUVWXYZ']
drives = ['%s:' % d for d in dl if os.path.exists('%s:' % d)]
def convert(list): 
  return tuple(list)
listdrive = convert(drives)

search_loc_var = tk.StringVar()
search_loc_cmbbx1 = ttk.Combobox(win, width = 22, textvariable = 
search_loc_var, state = 'readonly', values = drives)

# Defining the state readonly will restrict the user from typing anything 
# in the combobox.
search_loc_cmbbx1['values'] = listdrive
search_loc_cmbbx1.grid(row = 2, column = 1)

win.mainloop()

我试图从元组和列表中填充组合框。 但是组合框保持空白。

我想您想用本地PC上的现有驱动器垂直填充ttk.Combobox ，例如：

C:

D:

E:

为此，只需将dl转换为普通字符串即可

dl = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
