Update easyPythonpi.py

This Python module, easypythonpi.py, is designed to help with a variety of common calculations, including basic arithmetic operations, binary-to-decimal conversion, Fibonacci sequence generation, and shape area calculations. It is built with simplicity and ease of use in mind, making it ideal for both beginners and intermediate users. The module also includes custom exceptions to handle invalid inputs gracefully.
