What it does.

1. Accounts

   Your username and password live in a CSV. Log in if you've been here before, or make a new account on the same screen.
2. Transactions

   Add income and expenses, each with a date, an amount, a category, and a quick note. Pull them back up whenever.
3. Budgets

   Give each category a monthly budget and the program keeps a running tally of how much of it you've used.
4. Reports

   Summaries by month, by year, or by category. Line plots for income against spending, pie charts for where the money actually went.
5. Storage

   It all saves to CSV. Loads when you start, writes back when you leave, so nothing's gone the next time you open it.
6. Budget alerts

   A heads up when you're getting close to a category's limit, and a clearer one once you've gone over.
7. Error handling

   Checks your input and wraps the file stuff in try/except, so a missing CSV won't crash the whole thing.
8. Hidden passwords

   It uses getpass, so your password stays hidden instead of showing up as you type.

What's under the hood.

Built with Pandas·Matplotlib·Datetime·Calendar·Getpass·Sys. The rest is just plain Python.

Or run it on your own computer.

1. Grab the original notebook ICS4U_Project1.ipynb, or the .py version below.
2. Open it in anything that runs Python. Jupyter, VS Code, etc.
3. Run it and follow along with what it asks you. Have Fun!
