This is a simple Python console-based expense tracker. It demonstrates basic Python concepts such as functions, dictionaries, lists, loops, and user input handling. The program allows adding expenses, viewing a monthly summary, calculating total expenses, and generating a simple invoice.

Features

• Add an expense with category and amount (PKR)
• View a predefined monthly expense summary
• Calculate total expenses
