Python | pack() method in Tkinter Last Updated : 22 Feb, 2022 Comments Improve Suggest changes 15 Likes Like Report The Pack geometry manager packs widgets relative to the earlier widget. Tkinter literally packs all the widgets one after the other in a window. We can use options like fill, expand, and side to control this geometry manager.Compared to the grid manager, the pack manager is somewhat limited, but it’s much easier to use in a few, but quite common situations: Put a widget inside a frame (or any other container widget), and have it fill the entire framePlace a number of widgets on top of each otherPlace a number of widgets side by side Code #1: Putting a widget inside frame and filling entire frame. We can do this with the help of expand and fill options. Python3 # Importing tkinter module from tkinter import * from tkinter.ttk import * # creating Tk window master = Tk() # creating a Fra, e which can expand according # to the size of the window pane = Frame(master) pane.pack(fill = BOTH, expand = True) # button widgets which can also expand and fill # in the parent widget entirely # Button 1 b1 = Button(pane, text = "Click me !") b1.pack(fill = BOTH, expand = True) # Button 2 b2 = Button(pane, text = "Click me too") b2.pack(fill = BOTH, expand = True) # Execute Tkinter master.mainloop() Output: Code #2: Placing widgets on top of each other and side by side. We can do this by side option. Python3 # Importing tkinter module from tkinter import * # from tkinter.ttk import * # creating Tk window master = Tk() # creating a Fra, e which can expand according # to the size of the window pane = Frame(master) pane.pack(fill = BOTH, expand = True) # button widgets which can also expand and fill # in the parent widget entirely # Button 1 b1 = Button(pane, text = "Click me !", background = "red", fg = "white") b1.pack(side = TOP, expand = True, fill = BOTH) # Button 2 b2 = Button(pane, text = "Click me too", background = "blue", fg = "white") b2.pack(side = TOP, expand = True, fill = BOTH) # Button 3 b3 = Button(pane, text = "I'm also button", background = "green", fg = "white") b3.pack(side = TOP, expand = True, fill = BOTH) # Execute Tkinter master.mainloop() Output: Code #3: Python3 # Importing tkinter module from tkinter import * # from tkinter.ttk import * # creating Tk window master = Tk() # creating a Fra, e which can expand according # to the size of the window pane = Frame(master) pane.pack(fill = BOTH, expand = True) # button widgets which can also expand and fill # in the parent widget entirely # Button 1 b1 = Button(pane, text = "Click me !", background = "red", fg = "white") b1.pack(side = LEFT, expand = True, fill = BOTH) # Button 2 b2 = Button(pane, text = "Click me too", background = "blue", fg = "white") b2.pack(side = LEFT, expand = True, fill = BOTH) # Button 3 b3 = Button(pane, text = "I'm also button", background = "green", fg = "white") b3.pack(side = LEFT, expand = True, fill = BOTH) # Execute Tkinter master.mainloop() Output: Create Quiz Comment S sanjeev2552 Follow 15 Improve S sanjeev2552 Follow 15 Improve Article Tags : Python Python-tkinter Python-gui Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 2 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
