Expense Tracker 💻

Description ℹ️:

An implementation of 'Expense' and 'ExpenseDatabase' python classes, to model and manage financial expenses.

Expense 💳:

Represents an individual financial expense with the following attributes:

• id (str): A unique identifier generated as a UUID string.
• title (str): A string representing the title of the expense.
• amount (float): A float representing the amount of the expense.
• created_at (str): A timestamp indicating when the expense was created.
• updated_at (str): A timestamp indicating the last time the expense was updated.

ExpenseDatabase 💳💾:

Manages a collection of Expense objects, and has the following attribute:

• expenses (list): A list storing Expense instances.

Cloning 👯:

git clone https://github.com/jmorganp/alt-de-project-3.git

cd alt-de-project-3

Usage ⚙️:

You can import the Expense and ExpenseDatabase classes into your script (in the same directory) as follows:

from main import Expense, ExpenseDatabase

Then initialize them as follows:

expense_db = ExpenseDatabase() # create an expense database instance
monthly_expense = Expense('Altschool Tuition (Monthly)', 30.0)

To add the sample expense to the database:

expense_db.add_expense(monthly_expense)

To update the title & amount of the expense:

monthly_expense.update(title='Altschool Tuition (Monthly) (10% off)', amount=27.0)

You can perform the following operations on the Expense Database:

expense retrieval by id (UUID):

expense = expense_db.get_expense_by_id('607bd6a6-7838-414f-846b-0eb76d4504f9')

expense retrieval by title:

expense = expense_db.get_expense_by_title('Altschool Tuition (Monthly)')

expense removal (by id):

expense_db.remove_expense('607bd6a6-7838-414f-846b-0eb76d4504f9')

get expenses as a list of dictionaries:

expense_dict = expense_db.to_dict()

Or for convenience, just run the following in the terminal ⚡:

python main.py

Main guard 💂‍♂️ (code executed if you ran the script directly as specified above):

Requires 🧾:

Python >= 3.10
