from tkinter import*
import webbrowser

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

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

def save():
    with open("file.txt","w") as f:
        for i in listbox.get(0,END):
            f.write(i+"\n")
            #f.close()

def load():
    url = entry3.get()
    select=listbox.curselection()
    index=select[0]
    webbrowser.open(index)

read = open("file.txt","r")
data_list = read.readlines()
read.close()
data_list = [data.rstrip() for data in data_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()

推荐答案

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.另一个列表是保存文件中的url.这是看不到的，并且还需要同步它们.(save()，delete()，add()需要同时操作Listbox小部件和list).一个最小的例子.

You need to use two list.one list saves data in the file,this could be seen in the Listbox.The another list is to save the url in the file.this couldn't be seen.And also you need to synchronize them.(save(),delete(),add() need to operate both Listbox widget and the list).A minimal example.:

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()

在此示例中，文件中的格式:

In this example,the format in the file:

name : id  Url:xxxxxx

您还可以使用另一种方式保存它们并阅读它们.

You also could use another way to save them and read them.
