# Create table
cursor.execute('''
CREATE TABLE IF NOT EXISTS transactions (
    id INTEGER PRIMARY KEY,
    date TEXT,
    amount REAL,
    category TEXT,
    type TEXT
)
''')

def add_transaction(date, amount, category, type):
    cursor.execute('''
    INSERT INTO transactions (date, amount, category, type)
    VALUES (?, ?, ?, ?)
    ''', (date, amount, category, type))
    conn.commit()

def get_transactions():
    cursor.execute('SELECT * FROM transactions')
    return cursor.fetchall()

def main():
    while True:
        print("1. Add Transaction")
        print("2. View Transactions")
        print("3. Exit")
        choice = input("Enter your choice: ")
        if choice == '1':
            date = input("Enter date (YYYY-MM-DD): ")
            amount = float(input("Enter amount: "))
            category = input("Enter category: ")
            type = input("Enter type (income/expense): ")
            add_transaction(date, amount, category, type)
        elif choice == '2':
            transactions = get_transactions()
            for transaction in transactions:
                print(transaction)
        elif choice == '3':
            break

    'Vegetable Stir Fry': ['vegetables', 'soy sauce', 'garlic', 'ginger']
}

def recommend_recipes(ingredients):
    recommendations = []
    for recipe, ingredients_list in recipes.items():
        if all(ingredient in ingredients for ingredient in ingredients_list):
            recommendations.append(recipe)
    return recommendations

def main():
    user_ingredients = input("Enter your available ingredients (comma separated): ").split(',')
    user_ingredients = [ingredient.strip().lower() for ingredient in user_ingredients]
    recommendations = recommend_recipes(user_ingredients)
    if recommendations:
        print("We recommend the following recipes:")
        for recipe in recommendations:
            print(recipe)
    else:
        print("No recipes match your ingredients.")

if __name__ == "__main__":
    main()

Explanation: This Python script provides recipe suggestions based on the ingredients the user has on hand. It uses a simple dictionary to store recipes and their required ingredients.

3:Fitness Tracker Application

Overview: A Fitness Tracker Application helps users monitor their physical activities, track workouts, and set fitness goals.

Features:

• Track workouts and exercises.
• Log daily activity.
• Set and monitor fitness goals.

Source Code:

javascript
// Fitness Tracker Application using JavaScript and localStorage

class FitnessTracker {
    constructor() {
        this.activities = JSON.parse(localStorage.getItem('activities')) || [];
    }

    addActivity(date, type, duration) {
        this.activities.push({ date, type, duration });
        localStorage.setItem('activities', JSON.stringify(this.activities));
    }

    getActivities() {
        return this.activities;
    }
}

const tracker = new FitnessTracker();

function addActivity() {
    const date = prompt("Enter the date (YYYY-MM-DD):");
    const type = prompt("Enter the activity type:");
    const duration = prompt("Enter the duration (in minutes):");
    tracker.addActivity(date, type, duration);
    alert("Activity added!");
}

function viewActivities() {
    const activities = tracker.getActivities();
    console.log("Activities:");
    activities.forEach(activity => {
        console.log(`${activity.date} - ${activity.type}: ${activity.duration} minutes`);
    });
}

// Example usage
addActivity();
viewActivities();

Explanation: This JavaScript code uses localStorage to store and retrieve fitness activities. It includes functions to add and view activities, making it a useful tool for tracking fitness progress.
