如何加载 tkinter 的条目小部件中的 url，该小部件与列表框中列表的已保存用户输入链接？

Question

以下步骤描述了我的问题：
1. 打开应用程序
2. 输入姓名 = Mike ;身份证 = 11 ;网址 = www.google.com
3. 点击“添加”
4. 关闭应用程序。
5. 再次运行应用程序。
6. 在列表框中显示“Mike = 11”。
7. 但是当我选择“Mike = 11”并点击“加载”时，它并没有将我带到“www.google.com”，为什么？
请给我一些解决方案，告诉我如何打开带有已保存列表的 URL。
请帮助我！！

您需要使用两个列表。一个列表将data保存在文件中，这可以在Listbox中看到。另一个列表是将url保存在文件中。这个看不到.而且您还需要同步它们。（save(),delete(),add() 需要同时操作Listbox 小部件和list）。一个最小的例子。：

from tkinter import*
import webbrowser

def add():
    name = entry1.get()
    id = entry2.get()
    url = entry3.get()
    url_list.append(url)
    listbox.insert(END, name+ " : " +id)

def delete():
    select = listbox.curselection()
    index = select[0]
    url_list.pop(index)
    listbox.delete(index)

def save():
    with open("file.txt","w") as f:
        for i,j in zip(listbox.get(0,END),url_list):
            f.write(f"{i}  Url:{j}\n")

def load():
    select=listbox.curselection()
    index=select[0]
    load_url = url_list[index]
    webbrowser.open(load_url)

read = open("file.txt","r")
data_url_list = read.readlines()
read.close()
data_list = [data.rstrip().split("Url")[0] for data in data_url_list]
url_list = [data.rstrip().split("Url:")[1] for data in data_url_list]
win = Tk()
win.title("Class")

frame1=Frame(win)
frame2=Frame(win)
frame1.pack()
frame2.pack()

label1 = Label(frame1,text="Name : ")
label1.grid(row=0,column=0)

label2 = Label(frame1,text="Id : ")
label2.grid(row=1,column=0)

label3 = Label(frame1,text="Url : ")
label3.grid(row=2,column=0)

name = StringVar()
entry1 = Entry(frame1,textvariable=name)
entry1.grid(row=0,column=1)

id = StringVar()
entry2 = Entry(frame1,textvariable=id)
entry2.grid(row=1,column=1)

url = StringVar()
entry3 = Entry(frame1,textvariable=url)
entry3.grid(row=2,column=1)

scrollbar = Scrollbar(frame2,orient=VERTICAL)

listbox = Listbox(frame2,selectmode=EXTENDED,yscrollcommand=scrollbar.set,width=60)
listbox.pack()

scrollbar.config(command=listbox)

for item in data_list:
    listbox.insert(END,item)

button1 = Button(frame2,text="Add",command=add)
button1.pack()

button2 = Button(frame2,text="Delete",command=delete)
button2.pack()

button3 = Button(frame2,text="Save to File",command=save)
button3.pack()

button4 = Button(frame2,text="Load Url",command=load)
button4.pack()

win.mainloop()

在本例中，文件中的格式：

name : id  Url:xxxxxx

您也可以使用其他方式保存并阅读它们。
