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.")

if __name__ == "__main__":
main()
