Task Manager

Basic Task Manager in Python

class Task:
    def __init__(self, title, description):
        self.title = title
        self.description = description
        self.completed = False

    def complete(self):
        self.completed = True

    def __str__(self):
        status = "✓" if self.completed else "✗"
        return f"[{status}] {self.title}: {self.description}"


class TaskManager:
    def __init__(self):
        self.tasks = []

    def add_task(self, title, description):
        task = Task(title, description)
        self.tasks.append(task)
        print(f"Task '{title}' added.")

    def list_tasks(self):
        if not self.tasks:
            print("No tasks available.")
        for i, task in enumerate(self.tasks, start=1):
            print(f"{i}. {task}")

    def complete_task(self, index):
        if 0 <= index < len(self.tasks):
            self.tasks[index].complete()
            print(f"Task '{self.tasks[index].title}' completed.")
        else:
            print("Invalid task index.")

    def delete_task(self, index):
        if 0 <= index < len(self.tasks):
            removed_task = self.tasks.pop(index)
            print(f"Task '{removed_task.title}' deleted.")
        else:
            print("Invalid task index.")


def main():
    manager = TaskManager()

    while True:
        print("\nTask Manager")
        print("1. Add Task")
        print("2. List Tasks")
        print("3. Complete Task")
        print("4. Delete Task")
        print("5. Exit")

        choice = input("Choose an option: ")

        if choice == '1':
            title = input("Enter task title: ")
            description = input("Enter task description: ")
            manager.add_task(title, description)
        elif choice == '2':
            manager.list_tasks()
        elif choice == '3':
            index = int(input("Enter task index to complete: ")) - 1
            manager.complete_task(index)
        elif choice == '4':
            index = int(input("Enter task index to delete: ")) - 1
            manager.delete_task(index)
        elif choice == '5':
            print("Exiting Task Manager.")
            break
        else:
            print("Invalid choice. Please try again.")

    main()
