Python Calculator CTk (GUI)

Introduction

This project is a graphical user interface (GUI) calculator application built using the customtkinter library in Python. The calculator features both standard and programmer modes, offering functionalities for basic arithmetic operations, trigonometric calculations, and number system conversions (binary, decimal, hexadecimal, and octal).

Features

Standard Mode

• Basic arithmetic operations: addition, subtraction, multiplication, and division.
• Trigonometric functions: sine, cosine, tangent, arcsine, arccosine, and arctangent.
• Square and square root calculations.
• Percentage and plus/minus operations.
• Clear and erase functions.
• Switching between light and dark appearance modes.

Programmer Mode

• Number system conversions: binary, decimal, hexadecimal, and octal.
• Clear function.
• Switching between standard and programmer modes.
• Appearance mode options (light and dark).

Installation

To run this application, you'll need to have Python installed on your machine. You can install the required library 'customtkinter' using pip:

bash code

pip install customtkinter

Usage

Run the script to open the calculator application. You can switch between standard and programmer modes using the respective buttons provided in the GUI.
