如何从程序中保存信息然后使用它再次在程序中显示(简单编程) [英] How to save information from the program then use it to show in program again (simple programming)

问题描述

我有一个用户界面，我做的.它有条目表单和树视图部分.当我输入信息时，它会显示在树视图上(有 4 列的表格).但是当我关闭构建的 gui 时，这些信息消失了，然后当我再次构建时，树视图中没有显示任何信息.我不想将信息发送到数据服务器或任何云，我需要将其保存在我的本地驱动器或该程序所在的本地文件夹中.

尝试使用 pickle.

I have a user-interface, I made. It has Entry form and Treeview section. When I entry information, it show on the treeview (table with 4 column). But when I close the built gui, Those information disappear then when I build again no information show in treeview. I don't want to send information to data server or any clouds, I need save it in my local drive or local folder that this program locate.

Try it using pickle.

from tkinter import ttk, messagebox
import webbrowser as web

def addit() :
    web = website.get()
    us = user.get()
    pas = password.get()
    et = etc.get()

    info = [web,us,pas,'*'+et]
    tree.insert('','end',values=info)

def deleteit():
    item = tree.selection()
    tree.delete(item)

def contact():
    url='https://bit.ly/'
    web.open(url)

def on_closing():
    if messagebox.askokcancel("Quit", "Do you want to quit?"):
        x=[tree.item(x)['values'] for x in tree.get_children()]
        filehandler = open('data.pickle', 'wb')
        pickle.dump(x,filehandler)
        filehandler.close()
        window.destroy()
