I'm trying to write a code to get the name, salary, and age and show it in a list. I want this code have the feature of deleteing and editing the information. But in this step I don't know how delete or edit a particular information.
from tkinter import *
from tkinter import messagebox
from tkinter.ttk import *
i = 2
table_row = []
def getting():
global i
i = i + 1
data = []
var = IntVar()
c = Checkbutton(window, variable=var)
c.val = var
data.append(c)
c.grid(row=i, column=0)
value1=e11.get()
data.append(value1)
value2 = e22.get()
data.append(value2)
value3 = e33.get()
data.append(value3)
lblq = Label(window, text=data[1:])
lblq.grid(row=i, column=1)
table_row.append(data)
# print(table_row)
def delete_row():
for Noo, row in reversed(list(enumerate(table_row))):
if row[0].val.get() == 1:
for i in row:
i.destroy()
table_row(Noo)
window = Tk()
window.title("Table with add, edit and delete")
window.geometry('600x600')
def Closing():
res = messagebox.askokcancel("warning", "Are You sure!!!!!")
if res == True:
sys.exit()
############################################### #menu inside winodow
menu = Menu(window)
new_item = Menu(menu)
new_item.add_command(label="Exit", command=Closing)
menu.add_cascade(label='File', menu=new_item)
window.config(menu=menu)

lblsurname =Label(window, text="Salary")
lblsurname.place(x = 440,y = 180)

B2.place(x = 440,y = 90)
v0 = StringVar()
e0 = Entry(window, textvariable=v0, state='readonly')
v0.set('Select')
e0.grid(row=1, column=0)
v1 = StringVar()

v1.set('Information')
e1.grid(row=1, column=1)
window.mainloop()
Maybe I should use Class in my code, but I is difficult for me to use Class and tkinter simultaneously
You could use dictionary to keep single row - it would be more readable
When I add row I create dictionary with widgets and text from Entry, I add to list of rows and clear Entry.
If there is selected row in table then I don't create new row but replace text in selected row.
The same way I search selected row to copy text from row to Entry.
The same way I search selected row to remove row - destroy widgets and delete row on the list.
It is more easier to do it because I use dictionary to keep row and it is more readable.
