treeview ka branch wala form in python

 in this blog we are going to make the treeview form with the different branches in it so here are the following images to represent the data

# Python program to illustrate the usage

# of hierarchical treeview in python GUI

# application using tkinter

# Importing tkinter

from tkinter import *

# Importing ttk from tkinter

from tkinter import ttk

# Creating app window

app = Tk()

# Defining title of the app

app.title("GUI Application of Python")

# Defining label of the app and calling a geometry

# management method i.e, pack in order to organize

# widgets in form of blocks before locating them

# in the parent widget

ttk.Label(app, text ="Treeview(hierarchical)").pack()

# Creating treeview window

treeview = ttk.Treeview(app)

# Calling pack method on the treeview

treeview.pack()

# Inserting items to the treeview

# Inserting parent

treeview.insert('', '0', 'item1',

                text ='GeeksforGeeks')

# Inserting child

treeview.insert('', '1', 'item2',

                text ='Computer Science')

treeview.insert('', '2', 'item3',

                text ='GATE papers')

treeview.insert('', 'end', 'item4',

                text ='Programming Languages')

# Inserting more than one attribute of an item

treeview.insert('item2', 'end', 'Algorithm',

                text ='Algorithm')

treeview.insert('item2', 'end', 'Data structure',

                text ='Data structure')

treeview.insert('item3', 'end', '2018 paper',

                text ='2018 paper')

treeview.insert('item3', 'end', '2019 paper',

                text ='2019 paper')

treeview.insert('item4', 'end', 'Python',

                text ='Python')

treeview.insert('item4', 'end', 'Java',

                text ='Java')

# Placing each child items in parent widget

treeview.move('item2', 'item1', 'end')

treeview.move('item3', 'item1', 'end')

treeview.move('item4', 'item1', 'end')

# Calling main()

app.mainloop()
