## Overview

This is a small interactive command-line calculator. A user repeatedly selects an operation, enters numeric input, and sees a result; binary and unary operations are supported, including trigonometry and logarithms. All behavior lives in `calculator.py`: it validates input, dispatches through operation dictionaries, and prints results. The README lists the same capabilities. No separate storage or service layer exists.

Main entry points: [`calculator.py`](https://github.com/dhyanesh08/python-calculator/blob/main/calculator.py) (Interactive loop)
