Final Project: OOP Task Manager

Build a Full OOP Task Manager

Time to put everything together! This final project combines classes, exceptions, list comprehensions, and file handling into one complete, working task manager application.

YOUR TASK

Your program must include all of the following:

Classes

A Task class
Attributes: title, done
Constructor to set them

Methods

add_task(title)
complete_task(title)
list_tasks()
pending_count()

Exceptions

Raise ValueError if task not found
Use try/except around calls

Comprehensions

Use list comprehension in pending_count()
Show ✓ or ✗ per task

Architecture hint

Two-class structure:
class Task:
  def __init__(self, title): self.title = title; self.done = False

class TaskManager:
  def __init__(self): self.tasks = []
  def add_task(self, title): self.tasks.append(Task(title))
  def complete_task(self, title):
    for t in self.tasks:
      if t.title == title: t.done = True; return
    raise ValueError(f"Task not found: {title}")
  def pending_count(self):
    return len([t for t in self.tasks if not t.done])

Expected output:

✗ Buy groceries
✗ Write tests
✗ Read docs
