Python Tkinter Calculator

A simple GUI calculator built using Python and Tkinter.

Overview

This project is a basic calculator implemented with Python's Tkinter module. It supports basic arithmetic operations like addition, subtraction, multiplication, and division. The calculator also features a clear button to reset the input and basic error handling for invalid operations (e.g., division by zero).

Repository Structure

.
├── main.py
└── Components
    ├── Calculator_Entry.py
    └── Calculator_Button.py

• main.py: The main entry point that sets up the main window and integrates all components.
• Components/Calculator_Entry.py: Contains the definition of the Entry widget for user input and result display.
• Components/Calculator_Button.py: Contains the CalculatorButtons class that creates the calculator buttons and defines their functionality.

Features

• GUI-based Calculator: Built using Tkinter for a graphical user interface.
• Basic Arithmetic Operations: Supports addition (+), subtraction (-), multiplication (*), and division (/).
• Clear Functionality: A "CL" button to clear the current input.
• Error Handling: Displays "Error" when encountering division by zero or invalid input.
• Responsive Layout: Utilizes Tkinter's grid layout for a clean, organized interface.

Installation

Prerequisites

• Python 3.x installed on your system.
• Git (to clone the repository).

Steps

1. Clone the repository:

   git clone https://github.com/ParisaAlizadeh2003/calculator.git
   cd calculator

2. (Optional) Create and activate a virtual environment:

   python -m venv venv
   # On Windows:
   venv\Scripts\activate
   # On Unix or MacOS:
   source venv/bin/activate

3. Run the application:

   python main.py

Usage

• Launch the Calculator: Run main.py to start the application.
• Input Numbers and Operations: Use the on-screen buttons to enter numbers and arithmetic operators.
• Compute the Result: Press the = button to evaluate the expression and display the result.
• Clear Input: Press the CL button to clear the current input.
• Error Handling: If an error occurs (e.g., division by zero), the calculator displays "Error".

Future Improvements

• Enhanced UI/UX: Improve the design and layout with more advanced styling.
• Keyboard Support: Allow users to input numbers and operations via the keyboard.
• Additional Features: Support for advanced mathematical functions like square roots, percentages, etc.
• Calculation History: Implement a feature to display past calculations.
