Create a personalized birthday reminder tool

Here’s a simple personalized birthday reminder tool built with Python. It allows users to add birthdays, save them, and get reminders when a birthday is approaching.

python
CopyEdit
import datetime
import json
import os

BIRTHDAY_FILE = "birthdays.json"

def load_birthdays():
    if not os.path.exists(BIRTHDAY_FILE):
        return {}
    with open(BIRTHDAY_FILE, 'r') as file:
        return json.load(file)

def save_birthdays(birthdays):
    with open(BIRTHDAY_FILE, 'w') as file:
        json.dump(birthdays, file, indent=4)

def add_birthday(name, date_str):
    birthdays = load_birthdays()
    try:
        date = datetime.datetime.strptime(date_str, "%Y-%m-%d").date()
        birthdays[name] = date_str
        save_birthdays(birthdays)
        print(f"Birthday for {name} added.")
    except ValueError:
        print("Invalid date format. Use YYYY-MM-DD.")

def show_upcoming_birthdays(days_ahead=7):
    today = datetime.date.today()
    upcoming = []
    birthdays = load_birthdays()

    for name, date_str in birthdays.items():
        bday = datetime.datetime.strptime(date_str, "%Y-%m-%d").date()
        next_birthday = bday.replace(year=today.year)
        if next_birthday < today:
            next_birthday = next_birthday.replace(year=today.year + 1)
        delta = (next_birthday - today).days
        if 0 <= delta <= days_ahead:
            upcoming.append((name, next_birthday, delta))

    if upcoming:
        print("Upcoming Birthdays:")
        for name, bday, delta in sorted(upcoming, key=lambda x: x[2]):
            print(f"{name} - {bday.strftime('%B %d')} (in {delta} days)")
    else:
        print("No upcoming birthdays.")

def main():
    while True:
        print("nBirthday Reminder Tool")
        print("1. Add a birthday")
        print("2. Show upcoming birthdays")
        print("3. Exit")
        choice = input("Select an option: ")

        if choice == '1':
            name = input("Enter name: ")
            date = input("Enter birthday (YYYY-MM-DD): ")
            add_birthday(name, date)
        elif choice == '2':
            show_upcoming_birthdays()
        elif choice == '3':
            print("Goodbye!")
            break
        else:
            print("Invalid choice. Try again.")

if __name__ == "__main__":
    main()
