How I Built a Simple To-Do App Using Python

⚙️ What You'll Learn:

• Creating a Python menu-based app

• Working with lists

• Saving data to a file

• Reading and updating tasks

---

🛠️ Tools Used:

• Python 3.x

• Any code editor (I used VS Code)

• Terminal / Command Prompt

---

🧩 Step-by-Step Code Explanation:

✅ Step 1: Create the Main Menu

pythonCopyEditdef display_menu():
    print("\n--- To-Do List ---")
    print("1. View Tasks")
    print("2. Add Task")
    print("3. Remove Task")
    print("4. Exit")

📝 Step 2: Add & View Tasks

pythonCopyEdittasks = []

def add_task():
    task = input("Enter your task: ")
    tasks.append(task)
    print(f"Task '{task}' added!")

def view_tasks():
    if not tasks:
        print("No tasks added yet.")
    else:
        print("\nYour Tasks:")
        for idx, task in enumerate(tasks, 1):
            print(f"{idx}. {task}")

❌ Step 3: Remove a Task

pythonCopyEditdef remove_task():
    view_tasks()
    try:
        task_num = int(input("Enter task number to remove: "))
        if 1 <= task_num <= len(tasks):
            removed = tasks.pop(task_num - 1)
            print(f"Removed: {removed}")
        else:
            print("Invalid task number.")
    except ValueError:
        print("Please enter a valid number.")

🔁 Step 4: Run the App

pythonCopyEditwhile True:
    display_menu()
    choice = input("Enter your choice (1-4): ")

    if choice == "1":
        view_tasks()
    elif choice == "2":
        add_task()
    elif choice == "3":
        remove_task()
    elif choice == "4":
        print("Exiting... Bye!")
        break
    else:
        print("Invalid choice. Try again.")

💡 What I Learned:

• How to use functions to organize code

• How to work with lists and user input

• How loops and conditions help control program flow

---

🔚 Conclusion:

This was a fun and useful beginner project. If you're learning Python, try this out—it only takes 15–20 minutes, and you’ll understand so many key concepts in one go.

🔁 What’s Next?

I plan to upgrade this app by:

• Saving tasks to a file so they don't disappear

• Adding due dates or priorities

• Making a GUI using Tkinter or PyQt
