Tkinter is a standard GUI library for Python that provides a powerful object-oriented interface to the Tk GUI toolkit. It allows for the creation of GUI applications through widgets like buttons, labels, text boxes, and more. Tkinter applications start with importing the library and creating a main window with Tk(), then entering the main event loop with mainloop() to wait for and process events. Widgets can be organized and placed within the main window using geometry managers like pack(), grid(), and place(). Events can also be handled through binding Python functions to different widget events.

Python modules allow code reuse and organization. A module is a Python file with a .py extension that contains functions and other objects. Modules can be imported and their contents accessed using dot notation. Modules have a __name__ variable that is set to the module name when imported but is set to "__main__" when the file is executed as a script. Packages are collections of modules organized into directories, with each directory being a package. The Python path defines locations where modules can be found during imports.Python: Modules and Packages

Modules in Python allow organizing classes into files to make them available and easy to find. Modules are simply Python files that can import classes from other modules in the same folder. Packages allow further organizing modules into subfolders, with an __init__.py file making each subfolder a package. Modules can import classes from other modules or packages using either absolute or relative imports, and the __init__.py can simplify imports from its package. Modules can also contain global variables and classes to share resources across a program.Introduction to matplotlib

All data values in Python are encapsulated in relevant object classes. Everything in Python is an object and every object has an identity, a type, and a value. Like another object-oriented language such as Java or C++, there are several data types which are built into Python. Extension modules which are written in C, Java, or other languages can define additional types.
To determine a variable's type in Python you can use the type() function. The value of some objects can be changed. Objects whose value can be changed are called mutable and objects whose value is unchangeable (once they are created) are called immutable.Python functions

Tkinter is a Python binding to the Tk GUI toolkit. It is the standard Python interface to the Tk GUI toolkit,[1] and is Python's de facto standard GUI.[2] Tkinter is included with standard Linux, Microsoft Windows and macOS installs of Python.
The name Tkinter comes from Tk interface. Tkinter was written by Steen Lumholt and Guido van Rossum,[3] then later revised by Fredrik Lundh.[4]
Tkinter is free software released under a Python license.[5]
Description
As with most other modern Tk bindings, Tkinter is implemented as a Python wrapper around a complete Tcl interpreter embedded in the Python interpreter. Tkinter calls are translated into Tcl commands, which are fed to this embedded interpreter, thus making it possible to mix Python and Tcl in a single application.
There are several popular GUI library alternatives available, such as Kivy, Pygame, Pyglet, PyGObject, PyQt, PySide, and wxPython.
Some definitions
Window
This term has different meanings in different contexts, but in general it refers to a rectangular area somewhere on the user's display screen.
Top-level window
A window which acts as a child of the primary window. It will be decorated with the standard frame and controls for the desktop manager. It can be moved around the desktop and can usually be resized.
Widget
The generic term for any of the building blocks that make up an application in a graphical user interface.
Core widgets: The containers: frame, labelframe, toplevel, paned window. The buttons: button, radiobutton, checkbutton (checkbox), and menubutton. The text widgets: label, message, text. The entry widgets: scale, scrollbar, listbox, slider, spinbox, entry (singleline), optionmenu, text (multiline), and canvas (vector and pixel graphics).
Tkinter provides three modules that allow pop-up dialogs to be displayed: tk.messagebox (confirmation, information, warning and error dialogs), tk.filedialog (single file, multiple file and directory selection dialogs) and tk.colorchooser (colour picker).
Python 2.7 and Python 3.1 incorporate the "themed Tk" ("ttk") functionality of Tk 8.5.[6][7] This allows Tk widgets to be easily themed to look like the native desktop environment in which the application is running, thereby addressing a long-standing criticism of Tk (and hence of Tkinter). Some widgets are exclusive to ttk, such as the combobox, progressbar, treeview, notebook, separator and sizegrip.[8]
Frame
In Tkinter, the Frame widget is the basic unit of organization for complex layouts. A frame is a rectangular area that can contain other widgets.
Child and parent
When any widget is created, a parentchild relationship is created. For example, if you place a text label inside a frame, the frame is the parent of the label.
A minimal application
Here is a minimal Python 3 Tkinter application with one widget:[9]
#!/usr/bin/env python3
from tkinter import *
root = Tk() # Create the root (base) window
w = Label(root, text="Hello, world!") creating label by tkintrGraphical Programming in Python Using Tkinter

Automated Engineering of Domain-Specific Metamorphic Testing EnvironmentsPablo G坦mez Abajo

Context. Testing is essential to improve the correctness of software systems. Metamorphic testing (MT) is an approach especially suited when the system under test lacks oracles, or they are expensive to compute. However, building an MT environment for a particular domain (e.g., cloud simulation, model transformation, machine learning) requires substantial effort.
Objective. Our goal is to facilitate the construction of MT environments for specific domains.
Method. We propose a model-driven engineering approach to automate the construction of MT environments. Starting from a meta-model capturing the domain concepts, and a description of the domain execution environment, our approach produces an MT environment featuring comprehensive support for the MT process. This includes the definition of domain-specific metamorphic relations, their evaluation, detailed reporting of the testing results, and the automated search-based generation of follow-up test cases.
Results. Our method is supported by an extensible platform for Eclipse, called Gotten. We demonstrate its effectiveness by creating an MT environment for simulation-based testing of data centres and comparing with existing tools; its suitability to conduct MT processes by replicating previous experiments; and its generality by building another MT environment for video streaming APIs.
Conclusion. Gotten is the first platform targeted at reducing the development effort of domain-specific MT environments. The environments created with Gotten facilitate the specification of metamorphic relations, their evaluation, and the generation of new test cases.

In todays digital age, data has become an organizations lifeblood. As the use of digital technologies continues to escalate, so do the risks associated with personal data, which continue to grow exponentially as well. To effectively safeguard personal and sensitive information, organizations must understand the intricate relationship between data privacy, cybersecurity, and incident response.
Data privacy and cybersecurity are two sides of the same coin. Data privacy focuses on how personal data is to be collected, used, stored, shared and controlled, while cybersecurity aims to protect systems and networks from unauthorized access, digital attacks, malware and data breaches.
However, even with the best data privacy and security measures in place, cyber incidents can still occur. A well-prepared incident response plan is crucial for minimizing the impact of a breach and restoring normal operations.
Join our experts on this webinar to discuss how data privacy, cybersecurity, and incident response interact and are essential for safeguarding your organizations digital assets.
This webinar will review:
- How data privacy and cybersecurity intersect
- How to develop a comprehensive privacy and security strategy to safeguard personal and sensitive information
- What are suggestions and expectations around incident responseNetwork_Packet_Brokers_Presentation.pptx

AI is transforming talent acquisition by streamlining recruitment processes, enhancing decision-making, and delivering personalized candidate experiences. By automating repetitive tasks such as resume screening and interview scheduling, AI significantly reduces hiring costs and improves efficiency, allowing HR teams to focus on strategic initiatives. Additionally, AI-driven analytics help recruiters identify top talent more accurately, leading to better hiring decisions. However, despite these advantages, organizations must address challenges such as AI bias, integration complexities, and resistance to adoption to fully realize its potential. Embracing AI in recruitment can provide a competitive edge, but success depends on aligning technology with business goals and ensuring ethical, unbiased implementation.

The product triad is broken.
Not because of flawed frameworks, but because it rarely works as it should in practice.
When it becomes a battle of roles, it collapses.
It only works with clarity, maturity, and shared responsibility.Innovative Web Design | Malachite Technologies

I've been working on building a batch job framework for a few years now and blogging about it in the process. This presentation explains how and why I started building and writing about this system and the reason it changed from deploying one simple batch job to a much bigger project. I explore a number of recent data breaches, how they occurred, and what may have prevented them along the way. We consider how what make goes into an effective security architecture and well-designed security controls that avoid common pitfalls. There are friend links to many blog posts in the notes of the presentation that bypass the paywall. Topics include security architecture, IAM, encryption (KMS), networking, MFA, source control, separation of duties, supply chain attacks, and more.

- 1. Python GUI Luscious Larry Das
- 2. About Python GUI Python is an interactive programming which has multiple options for developing GUI (Graphical User Interface). Some of them are 1. Kivy - Linux, Windows, OS X, Android, IOS, Raspberry Pi 2. PyQT - Linux, Windows, OS X, Android, IOS 3. PyForms - Linux, Windows, OS X 4. WxPython - Linux, Windows, OS X 5. Tkinter - Linux, Windows, OS X
- 3. About Tkinter Tkinter is the standard GUI library for Python. Python when combined with Tkinter provides a fast and easy way to create GUI applications. Tkinter provides a powerful object-oriented interface to the Tk GUI toolkit. Its built in library so no need to install. Just need to import.
- 4. How it work? 1. Tk() - To create a main window, tkinter offers a method Tk() 2. mainloop() - is an in鍖nite loop used to run the application, wait for an event to occur and process the event as long as the window is not closed.
- 5. Widget Tkinter provides various controls, such as buttons, labels and text boxes used in a GUI application. There are currently 15 types of widgets in Tkinter. 1. Button 6. Label 11. Radiobutton 2. Canvas 7. Listbox 12. Scrollbar 3. Checkbutton 8. Menubutton 13. Text 4. Entry 9. Menu 14. Toplevel 5. Frame 10. Message 15. PhotoImage
- 6. Geometry Con鍖guration Tkinter offers access to the geometric con鍖guration of the widgets which can organize the widgets in the parent windows. There are mainly three geometry manager classes class. 1. pack() - organizes the widgets in blocks 2. grid() - organizes the widgets in grid (table-like structure) 3. place() - organizes the widgets by placing them on speci鍖c positions
- 7. How to add widgets? Button(window, option=value) - Options (activebackground, activeforeground, bg, command, font, image, height, width)
- 8. Image Widget Tkinter user PhotoImage() to display images. But with this widget we only can display GIF images. To display other format images we need to install pillow package. Example code on pillow
- 9. Events and Binds Tkinter provides a mechanism to let the programmer deal with events. For each widget, it's possible to bind Python functions and methods to an event. widget.bind(event, handler) If the de鍖ned event occurs in the widget, the "handler" function is called with an event object. describing the event.
- 10. Events List 1. <Button>: <Button-1>(left), <Button-2>(middle), <Button-3>(right), <Button-4>(scroll up), <Button-5>(scroll down) 2. <Double-Button>: <Double-Button-1>(left), <Double-Button-2>(middle), <Double-Button-3>(right) 3. <Enter> 4. <Leave> 5. <Return> 6. <Key>
