如何添加带有Button的新输入字段？输入字段由Python Tkinter中的循环创建

import tkinter as tk

def add_field():
    # 创建新的输入字段和Button
    entry = tk.Entry(root)
    entry.pack()
    button = tk.Button(root, text="删除", command=lambda: remove_field(entry, button))
    button.pack()
    fields.append((entry, button))

def remove_field(entry, button):
    # 删除输入字段和Button
    entry.pack_forget()
    button.pack_forget()
    fields.remove((entry, button))

root = tk.Tk()
fields = []

# 创建初始的输入字段和Button
entry = tk.Entry(root)
entry.pack()
button = tk.Button(root, text="删除", command=lambda: remove_field(entry, button))
button.pack()
fields.append((entry, button))

# 添加新的输入字段和Button的按钮
add_button = tk.Button(root, text="添加", command=add_field)
add_button.pack()

root.mainloop()
