Project Name: Expense Tracker
Objective: The objective of the Expense Tracker project is to create a simple yet functional application to help users manage their personal finances by tracking their expenses. The application allows users to add, list, and filter expenses based on categories, as well as calculate the total expenses.
Users can add an expense by entering the amount and category. Each expense is stored as a dictionary with 'amount' and 'category' keys in a list.
Users can view all the expenses they have added. The expenses are displayed with the amount and category.
The application calculates and displays the total amount of all expenses added.
Users can filter expenses by a specific category. The filtered expenses are displayed with the amount and category.
Users can exit the application.
The application is written in Python. It uses basic data structures like lists and dictionaries to store and manage expenses. The program runs in a loop, allowing users to continuously interact with the application until they choose to exit. Functions:
