Basic Calculator with Tkinter

This project is a simple calculator application built using Python's tkinter library. The goal is to demonstrate how to create a graphical user interface (GUI) for performing basic arithmetic operations.

About the Project

The calculator will have a clean and user-friendly interface, allowing users to perform operations such as addition, subtraction, multiplication, and division. This project is suitable for beginners looking to learn how to use tkinter to build desktop applications.

Basic Operations of Tkinter

Tkinter is Python's standard library for creating GUI applications. Below are some of the core components and operations used in this project:

1. Creating the Main Window

   • The Tk() class is used to create the main application window.
   • Example:

     from tkinter import Tk
     root = Tk()
     root.title("Basic Calculator")
     root.mainloop()

2. Adding Widgets

   • Widgets are the building blocks of a Tkinter application.
   • Common widgets used in this project include:
     • Label: To display text or instructions.
     • Entry: For user input.
     • Button: For interactive elements.

3. Using Layout Managers

   • Tkinter provides layout managers to arrange widgets in the window:
     • pack(): Places widgets in a block.
     • grid(): Places widgets in a table-like structure.
     • place(): Places widgets at an absolute position.

4. Handling Events

   • Button clicks and other user actions are handled using event binding.
   • Example:

     def on_button_click():
         print("Button clicked!")
     
     button = Button(root, text="Click Me", command=on_button_click)
     button.pack()

5. Configuring Widgets

   • Widgets can be customized using properties like text, font, bg (background), and fg (foreground).

6. Running the Main Event Loop

   • The mainloop() method starts the Tkinter application and waits for user interaction.
