问题
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.

These is a simple program that I created for my personal life. If you have some suggestions to this concept, please leave it below

Try it using pickle.
from tkinter import *
from tkinter import ttk, messagebox
import webbrowser as web
import pickle
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()

window = Tk()

window.title('Password \'s Book')
window.iconbitmap('icon.ico')
menu=Menu(window)
menucontact = Menu(window, tearoff=0)
menucontact.add_command(label='Contact us',command = contact)
menu.add_cascade(label='Contact us',menu=menucontact)

Header =['Website','Username','Password','etc']
tree=ttk.Treeview(window, height=15,column=Header , show='headings')
tree.grid(row=6,column=0,padx=5,pady=5)
#------------Add Header---------------
for col in Header :
tree.column(col,width=80)
tree.heading(col,text=col.title())
items = []
try:
filehandler = open('data.pickle', 'rb')
items = pickle.load(filehandler)
filehandler.close()
except:
pass
for item in items:
tree.insert('','end',values=item)
window.protocol("WM_DELETE_WINDOW", on_closing)
window.mainloop()
回答2:
Add following code at the end of addit function (move imports at the top of the module):
import os
import json
def addit():
# ...
with open(os.path.join(os.path.dirname(__file__), "mydata.json"), "a") as data_file:
json.dump(info, data_file)
and create another function:
def populate():
with open(os.path.join(os.path.dirname(__file__), "mydata.json"), "r") as data_file:
info = json.load(data_file)
for elem in info:
tree.insert('','end',values=elem)
and call it before mainloop call.
