Final Capstone Project: Personal Expense Management System

Objective: Develop a comprehensive command-line application in Python that allows users to track their daily expenses, categorize them, and manage data persistence through file operations. This project serves as the culmination of the Python Foundation Program and requires the application of variables, data structures, loops, conditionals, functions, and file I/O. Step-by-step instructions: 1. Setup: Initialize a main menu using a while loop that offers users choices to add an expense, view all expenses, calculate totals, save data, and exit. 2. Data Entry: Create a function to capture user input for the expense amount (float), category (string), and date (string). 3. Data Structure: Use a list of dictionaries to store each expense record during the session. 4. Persistence: Implement functionality to save the list to a text or CSV file and a corresponding function to load that data when the program starts. 5. Logic: Add a feature to filter expenses by category or to find the highest spending category. 6. Validation: Use try-except blocks to handle instances where users provide invalid data types (e.g., text instead of a number for an amount).
