Tkinter is a Python wrapper for Tcl/Tk providing a cross-platform GUI toolkit. On Windows, it comes bundled with Python; on other operating systems, it can be installed. The set of available widgets is smaller than in some other toolkits, but since Tkinter widgets are extensible, many of the missing compound widgets can be created using the extensibility, such as combo box and scrolling pane.IDLE, Python's Integrated Development and Learning Environment, is written using Tkinter and is often distributed with Python. You can learn about features of Tkinter by playing around with menus and dialogs of IDLE. For instance, Options Configure IDLE.
Dialog shows a broad variety of GUI elements including tabbed interface. You can learn about programming using Tkinter by studying IDLE source code, which, on Windows, is available e.g.

Options For Python GUI Programming a. TkinterPython ships with the Tk GUI toolkit. Tkinter is an interface to this. PyQtA Python binding of the cross-platform GUI toolkit Qt, PyQt is implemented as a plug-in for Python. WxPythonwxWidgets is a cross-platform GUI API for Python; wxPython is a wrapper for this. What is the Python Tkinter?Tkinter in Python GUI Programming is standard Python GUI library. It gives us an object-oriented interface to the Tk GUI toolkit.So, let’s start Python graphics, let’s create a simple GUI application:.
Import the module Tkinter. Create the main window for the application.
Add a widget or more. Enter the main event loop to deal with an event when it is triggered. import tkinter top=tkinter.Tk top.mainloopNow, this creates the following window. An output of Adding a Menu Button i. MenuThis lets us put all kinds of menus in our application. Python GUI Programming with TkinterSo, this was all about Python GUI Programming. Hope you like our explanation of Tkinter Tutorial in Python 3.5.
