Expense Tracker CLI

A small command-line tool to track daily expenses, written in Python with the standard library only (no dependencies). Expenses are stored in a local CSV file.

Features

• Add an expense (amount + category, auto-dated)
• View all expenses in a numbered table
• Total spent, with a per-category breakdown
• Delete an expense by its number
• CSV storage — your data lives in expenses.csv

Run it

python3 expense_tracker.py

No installation needed (Python 3 standard library only). A menu appears:

--- Expense Tracker ---
1. Add Expense
2. View Expenses
3. Show Total
4. Delete Expense
5. Exit
Enter choice:

Example — after adding a few expenses:

Total Spent: 157.50
By category:
  Rent            100.00
  Food            57.50

How it works

Expenses are read/written with Python's csv.DictReader / csv.DictWriter, so the header row is handled automatically. add appends a row; delete rewrites the file without the chosen row. Data persists in expenses.csv in the current directory.
