Python GUI App is not functioning well, help me fix it?

Here's my code of a gui app using tkinter library, it creats tables and prints orders for each table and gives the ability to edit orders on every table. the goal of it to know what did each table order. but editing the orders doesn't seem to work at all, I need help fixing it.
import tkinter as tk
class TableOrdersApp:
def __init__(self, master):
self.tables = []
self.table_list = tk.Listbox(master)
self.table_list.pack(side=tk.LEFT, fill=tk.BOTH)
self.table_list.bind("<<ListboxSelect>>", self.refresh_label)
self.orders_label = tk.Label(master, text="", anchor=tk.W, justify=tk.LEFT, wraplength=400)
self.orders_label.pack(side=tk.LEFT, fill=tk.BOTH, expand=True)
self.button_frame = tk.Frame(master)
self.button_frame.pack(side=tk.RIGHT)
self.add_button = tk.Button(self.button_frame, text="Add Table", command=self.add_table)
self.add_button.pack(side=tk.TOP)
self.remove_button = tk.Button(self.button_frame, text="Remove Table", command=self.remove_table)
self.remove_button.pack(side=tk.TOP)
self.edit_button = tk.Button(self.button_frame, text="Edit Order", command=self.edit_order)
self.edit_button.pack(side=tk.TOP)
self.remove_order_button = tk.Button(self.button_frame, text="Remove Order", command=self.remove_order)
self.remove_order_button.pack(side=tk.TOP)
def add_table(self):
self.tables.append([])
self.table_list.insert(tk.END, "Table {}".format(len(self.tables)))
def remove_table(self):
index = self.table_list.curselection()[0]
self.tables.pop(index)
self.table_list.delete(index)
def refresh_label(self, event=None):
self.orders_label.config(text="\n".join(self.tables[self.table_list.curselection()[0]]))
def edit_order(self):
index = self.table_list.curselection()[0]
orders = self.tables[index]
if self.orders_label.select_present():
start_index = self.orders_label.index(tk.SEL_FIRST)
end_index = self.orders_label.index(tk.SEL_LAST)
selected_text = self.orders_label.selection_get()
num_newlines = selected_text.count("\n")
order_index = start_index.split(".")[0] - 1 - num_newlines
new_order = tk.simpledialog.askstring("Edit Order", "Enter the new order:")
orders[order_index] = new_order
self.refresh_label()
def remove_order(self):
index = self.table_list.curselection()[0]
orders = self.tables[index]
start_index = self.orders_label.index(tk.SEL_FIRST)
end_index = self.orders_label.index(tk.SEL_LAST)
num_newlines = self.orders_label.get(start_index, end_index).count("\n")
order_index = start_index.split(".")[0] - 1 - num_newlines
orders.pop(order_index)
self.refresh_label()
# Create the main window
root = tk.Tk()
# Create an instance of the TableOrdersApp class
app = TableOrdersApp(root)
# Run the main loop of the app
root.mainloop()
I tried to make it print a label and make it editable using "edit order" button, but the button itself doesn't seem to work, and I want it to print "Empty" if the table has no orders how can i do that.

Look in edit_order and remove_order function. Must easier to write less coding.
Here is code:
import tkinter as tk
class TableOrdersApp:
def __init__(self, master):
self.tables = []
self.table_list = tk.Listbox(master)

how to make a button with a different number in tkinter

im trying to name a button what it is named in ent and so it doesn't repeat when the button is pressed again so if you press once it's button1 and again button2
from tkinter import *
def ext():
win1.destroy()
but1 = Button(root, text=txt.get(), height=10, width=30)
but1.grid(padx=3, row=0, column=1)
def create():
global win1
global txt
win1 = Tk()
win1.geometry("200x200")
ent = Entry(win1)
ent.pack(pady=20)
txt = ent.get()
sub = Button(win1, text="Submit", command=ext)
sub.pack()
root = Tk()
root.geometry("750x750")
root.config(background="#6673ED")
create_but = Button(root, text="Create new card", height=10, width=30, command=create)
create_but.grid(row=0,column=0)
root.mainloop()

The code below uses a dictionary of lists to add an integer to any repeating text input. I think this is what the question is about.
import tkinter as tk # import as tk is safer and more flexible
# Globals to keep it simple
names = {} # Dictionary. Will become a dictionary of lists.
row = 1
col = 0
win1 = None
ent = None
def add_text( txt ):
""" Adds txt to the names dictionary if it doesn't already exist.
Adds and integer to the txt if it does already exit """
name = names.get( txt, None )
if name:
name.append( txt + str(len( name )) ) # Append `txt + int` to a list
else:
names[ txt ] = [ txt ] # Add a list of one item to the dict.
# print( names ) # Uncomment to see what is happening.
return names[ txt ][-1]
def ext():
global row, col
txt = ent.get() # Get the text from the entry
win1.destroy() # before the window is destroyed
txt = add_text( txt )
but1 = tk.Button(root, text=txt, height=10, width=30)
but1.grid(padx=3, row=row, column=col) # row and column need to
# change to show all buttons.

ent.pack(pady=20)
ent.focus() # Position the focus in the Entry
# txt = ent.get() # removed as the Entry was being read before data was entered.
# The entry is now read in `ext`.

If anything is unclear please ask I really need help.
Thanks in advance!

Hi and welcome to Stack Overflow. For you to know which data is selected with the mouse, you can use the following way:
name_of_listbox.curselection()
This will return a list of the contents of the rows currently selected. It gives us a list because there is an option to select multiple rows of data in a ListBox.
You can iterate through each and grab the data out of them.
Store the data in a variable and use them for UPDATE and DELETE commands.
EDIT:
For deleting records:
f_name = listbox.curselection()[0]
l_name = listbox.curselection()[1]
number = listbox.curselection()[2]
c1.execute("DELETE * FROM Kontakti WHERE f_name = ? AND l_name = ? AND number = ?", (f_name, l_name, number))
conn1.commit()
For modifying the values:
c1.execute("UPDATE Kontakti SET f_name=?, l_name=?, number=? WHERE f_name= ? AND l_name = ? AND number=?",(new_value_for_f_name,new_value_for_l_name,new_value_for_number, f_name, l_name, number))
conn1.commit()
I quite did not get the way you were selecting first name, last name and number from a single listbox. So I have kept the name of the listbox the same.

You are using literal sql script and basically you can delete and update like below.
An advice ORM (Object Relational Mapping) is more effortless rather than raw query.
For Delete
DELETE <TableName> WHERE Id = <Value>
conn = sqlite3.connect("Imenik.db")
c = conn.cursor()
sql = "DELETE TableName WHERE Id = ?"
id = 1
c.execute(sql, (id,))
For Update
UPDATE <TableName> SET <ColumnName> = <NewValue> WHERE Id = <Value>
conn = sqlite3.connect("Imenik.db")
c = conn.cursor()
sql = "UPDATE TableName SET ColumnName = ? WHERE Id = ?"
id = 1
new_value = 'hello'
# params order left to right (important).
c.execute(sql, (new_value, id))

How To Save a key to a dictionary forever?

iam trying to make a phonebook using python and tkinter . I need to add new numbers to my phonebook
by adding elements to the dictionary but i can't access the numbers again after the programme is closed .
from tkinter import*

this is my code,what to do?

Variables in Python are not saved to disk, they only exist in memory (RAM) unless you explicitly save it there yourself.
You can either save to a file directly or, use a database instead.
See Here for using Pickle to do what you want.

How get value from Tkinter Var in class?

I'm trying to put old school sequential Tkinter code into class structure code.
So let's consider this example :
import Tkinter as Tk
def StartProcess():
print Text_1_Var.get(), Text_2_Var.get(), Text_3_Var.get()
if __name__ == '__main__':
MainFrame = Tk.Tk()
Tk.Button(MainFrame , text = "Start",command=StartProcess).grid(column=2, row=0)
Tk.Label(MainFrame , text = "1").grid(column=1, row=1)
Text_1_Var = Tk.StringVar()
Text_1 = Tk.Entry(MainFrame , width=40, textvariable = Text_1_Var).grid(column=2, row=1)
Tk.Label(MainFrame , text = "2").grid(column=1, row=2)
Text_2_Var = Tk.StringVar()
Text_2 = Tk.Entry(MainFrame , width=40, textvariable = Text_2_Var).grid(column=2, row=2)
Tk.Label(MainFrame , text = "3").grid(column=1, row=3)
Text_3_Var = Tk.StringVar()
Text_3 = Tk.Entry(MainFrame , width=40, textvariable = Text_3_Var).grid(column=2, row=3)
# etc
MainFrame.mainloop()
On press "Start" it displays values of Entry from 1 to 3.
Now i recode it as follow :
import Tkinter as Tk
def StartProcess():
print "???"
class NewEntry(Tk.Frame):
def __init__(self,master=None,idnumber=None):
Tk.Frame.__init__(self,master)
self.pack(side=Tk.TOP)
self.CreateWidgets(idnumber)
def CreateWidgets(self,idnumber):
Tk.Label(master=self, text = idnumber).grid(column=1, row=0)
self.Text_Var = Tk.StringVar()
self.Text = Tk.Entry(master=self, width=40, textvariable = self.Text_Var).grid(column=2, row=0)
if __name__ == '__main__':
MainFrame = Tk.Tk()
Tk.Button(master=MainFrame,text="Start", command=StartProcess).pack()
for i in range (1, 4): # or more
NewEntry(master=MainFrame,idnumber=str(i))
MainFrame.mainloop()
GUI are both identical. I want to get the same result but i don't know where my function StartProcess should take place and how extract value of each self.Text_Var instance.

It's not enough to create a NewEntry object; you need to save references to them so you can access them later (e.g., from StartProcess).
entries = []
for i in range (1, 4): # or more
e = NewEntry(master=MainFrame,idnumber=str(i))
entries.append(e)
# Or more simply,
# entries = [NewEntry(master=MainFrame, idnumber=str(i)) for i in range(1,4)]
Then, StartProcess becomes something like
def StartProcess():
strings = [x.Text_Var.get() for x in entries]
print " ".join(strings)
