Create a budget tracker with alerts

Here’s a simple but functional Budget Tracker with Alerts built using Python. It allows users to:

• Add income and expenses

• Track balances

• Set a budget limit

• Get an alert when the budget is close to or exceeds the limit

import datetime

class BudgetTracker:
    def __init__(self, budget_limit):
        self.transactions = []
        self.budget_limit = budget_limit
        self.balance = 0.0

    def add_income(self, amount, description=""):
        self.transactions.append({
            "type": "income",
            "amount": amount,
            "description": description,
            "date": datetime.datetime.now()
        })
        self.balance += amount
        self._check_alert()

    def add_expense(self, amount, description=""):
        self.transactions.append({
            "type": "expense",
            "amount": amount,
            "description": description,
            "date": datetime.datetime.now()
        })
        self.balance -= amount
        self._check_alert()

    def _check_alert(self):
        spent = sum(t["amount"] for t in self.transactions if t["type"] == "expense")
        if spent >= self.budget_limit:
            print("⚠️ ALERT: Budget limit exceeded!")
        elif spent >= 0.9 * self.budget_limit:
            print("⚠️ WARNING: You are close to your budget limit.")

    def show_summary(self):
        income = sum(t["amount"] for t in self.transactions if t["type"] == "income")
        expense = sum(t["amount"] for t in self.transactions if t["type"] == "expense")
        print(f"Total Income: ${income:.2f}")
        print(f"Total Expenses: ${expense:.2f}")
        print(f"Current Balance: ${self.balance:.2f}")
        print(f"Budget Limit: ${self.budget_limit:.2f}")

    def show_transactions(self):
        print("nTransaction History:")
        for t in self.transactions:
            print(f"{t['date'].strftime('%Y-%m-%d %H:%M:%S')} - {t['type'].capitalize()}: ${t['amount']:.2f} - {t['description']}")

# Example usage:
tracker = BudgetTracker(budget_limit=1000)

tracker.add_income(1500, "Salary")
tracker.add_expense(200, "Groceries")
tracker.add_expense(600, "Rent")
tracker.add_expense(150, "Utilities")

tracker.show_summary()
tracker.show_transactions()

Features:

• Budget limit alert when expenses reach or exceed 90% of the limit.

• Easy summary of income, expenses, and balance.

• Transaction history with timestamps.
