Question

我想制作一个列表框来列出用户.conf文本文件。你知道吗

如何列出它来选择要删除的帐户？你知道吗

• 你知道吗用户.conf地址：
• 56185用户密码==“56185”
• 40317用户密码==“40317”
• 11581用户密码==“11581”
• 38467用户密码==“38467”
• 50071用户密码==“50071”

• 81045用户密码==“81045”

• 列表框中的首选输出：

• 56185个
• 40317号
• 11581个
• 38467个
• 50071个

• 81045个

  def deleteuser():
     with open('C:/FreeRADIUS.net/etc/raddb/users.conf', "r") as fh:
      lines = fh.readlines()
     with open('C:/FreeRADIUS.net/etc/raddb/users.conf', "w") as fh:
      for line in lines:                  
          if deleteuserentry.get() in line and  deleteuserpwd.get() == "Pa$$w0rd123" :
             tkMessageBox.showinfo("success", "Account Deleted")
             end()
  
  
      deleteteuser = ttk.Label(page1, text="Delete User").grid(column=0, row=6, sticky='W')
      deleteusername = ttk.Label(page1, text="Enter current user's username:").grid(column=0, row=7, sticky='W')
      deleteuserentry = ttk.Listbox(page1, selectmode = BROWSE)
      deleteuserentry.grid(row=7, column=1, columnspan=2)
      for lines in ('C:/FreeRADIUS.net/etc/raddb/users.conf', "r"):
          lb.insert(END,line)
      deleteuserpassword = ttk.Label(page1, text="Enter Administrator's password:").grid(column=0, row=8, sticky='W')
      deleteuserpwd = ttk.Entry(page1, show='*')
      deleteuserpwd.grid(row=8, column=1, columnspan=2)
      deleteuserconfirm = Button(page1, text='Delete this User', borderwidth=2, command= deleteuser)
       deleteuserconfirm.grid(row=9, column=0, sticky='W')
      du = Button(page1, text='import file to delete multiple accounts', borderwidth=2, command= du)
      du.grid(row=9, column=2, sticky='E')

您可以通过regex匹配行，在开始处选择用户id，并将行数据填充到一个列表中。当从列表框中删除一个项目时，用户id将附加到另一个列表中。当接口关闭时，会发生从文件中删除的实际操作。这是我的意思的结构。你可以用它作为一个例子-在需要的地方进行优化。你知道吗

import re
import os
from tkinter import *

pattern = re.compile(r'^(?P<user_id>\d+)\s')
data_file = 'users.conf'
res_file = 'result.conf'  # This could alse be the same file from which the users are read

try:
    os.remove(res_file)
except FileNotFoundError:
    pass

# Read users
with open(data_file) as f:
    lines = []

    for l in f.readlines():
        match = pattern.match(l)
        if match is not None:
            user_id = match.group('user_id')
        else:
            user_id = ''
        lines.append((user_id, l))


lines_to_remove = []


def delete_record(lb):
    user_id = lb.get(ANCHOR)
    lines_to_remove.append(user_id)
    lb.delete(ANCHOR)


# Display GUI
top = Tk()
lb = Listbox(top)
b = Button(top, text="Delete",
           command=lambda lb=lb: delete_record(lb))

for line in lines:
    if line[1]:
        lb.insert(END, line[0])

lb.pack()
b.pack()
top.mainloop()

# Delete lines
valid_lines = filter(lambda l: l[0] not in lines_to_remove, lines)
with open(res_file, 'w+') as f:
    f.writelines([l[1] for l in valid_lines])
