def save():
    info = {}
    info['Name'] = entry_name.get()
    info['Family'] = entry_family.get()
    if country1.get() == 1:
        info['Country_1'] = 'Italy'
    elif country1.get() == 2:
        info['Country_1'] = 'France'
    elif country1.get() == 3:
        info['Country_1'] = 'Germany'
    if country2.get() == 1:
        info['Country_2'] = 'Romania'
    elif country2.get() == 2:
        info['Country_2'] = 'Greek'
    elif country2.get() == 3:
        info['Country_2'] = 'Poland'
    info['Age'] = spin_age.get()
    if left_hand.get() == 1:
        info['Left_hand'] = 'is left hand'
    else:
        info['Left_hand'] = 'is right hand'
    f = open('information', 'a')
    f.write(str(info))
    f.write('\n')
    f.close()
app = Tk()
app.geometry('400x300')
spin_age = Spinbox(app, from_ = 1, to = 100, bg='pink', state='readonly')

label_name = Label(app, text='name: ')
label_family = Label(app, text='family: ')
label_name.grid(row = 1, column=1)
label_family.grid(row = 2, column=1)
entry_name = Entry(app)
entry_family = Entry(app)
entry_name.grid(row=1, column=2)
entry_family.grid(row=2, column=2)
country1 = IntVar()
country2 = IntVar()
rb_italy = Radiobutton(app, text='Italy', variable=country1, value = 1)
rb_france = Radiobutton(app, text='France', variable=country1, value = 2)
rb_germany = Radiobutton(app, text='Germany', variable=country1, value = 3)
rb_romania = Radiobutton(app, text='Romania', variable=country2, value = 1)
rb_greek = Radiobutton(app, text='Greek', variable=country2, value = 2)
rb_poland = Radiobutton(app, text='Poland', variable=country2, value=3)
rb_italy.grid(row = 3, column=1, sticky='W')
rb_france.grid(row = 4, column=1, sticky='W')
rb_germany.grid(row = 5, column=1, sticky='W')
rb_romania.grid(row = 3, column=2, sticky='W', padx=10)
rb_greek.grid(row = 4, column=2, sticky='W', padx=10)
rb_poland.grid(row = 5, column=2, sticky='W', padx=10)
left_hand = IntVar()
chbox_left_hand = Checkbutton(app, text='I am left hand', variable=left_hand)
chbox_left_hand.grid(row = 6, column=1, pady=10)
btnExit = Button(app, text='Exit', command=myexit)
btnsave = Button(app, text='save', command=save)
spin_age.grid(row=1, rowspan=2, column=3, sticky='NS')
btnExit.grid(row=100, column=1)
btnsave.grid(row=100, column=2)
btnread = Button(app , text = 'saved info' , command = readbtn)
btnread.place(x = 70 , y = 200)
app.mainloop()

the save button well save the info i gave but i need a button to read the info

To read saved info, you need to do the exact opposite to what you did when you saved it. So open the file, read its contents, [convert the string to a dict](https://stackoverflow.com/questions/988228/convert-a-string-representation-of-a-dictionary-to-a-dictionary) and set the widgets to correspond to the values in the dict. What have you tried and which part exactly do you need help with? — fhdrsdg, Sep 01 '21 at 11:57
Please trim your code to make it easier to find your problem. Follow these guidelines to create a [minimal reproducible example](https://stackoverflow.com/help/minimal-reproducible-example). — Community, Sep 04 '21 at 09:18
