In this tutorial, we’ll build a command-line task manager using Python. Task managers are great for learning programming basics like user input, loops, conditionals, and lists. By the end, you'll have a working task manager where you can add, view, update, and delete tasks.

Setting up the Development Environment 🖥️

Choosing a programming language is crucial. Python is versatile for web development, software, math, and system scripting. To start, make sure you have Python installed. Download Python.

1. Install an IDE: We’ll use Visual Studio Code for code writing, debugging, and compiling. Download VS Code.

Project Initialization 🚀

With everything set up, create a directory and a Python file:

mkdir task_manager
cd task_manager
touch task_manager.py

This will be your main file where the task management logic goes.

Implementing the Features ✨

Adding Tasks ➕

Here’s a function to add tasks:

tasks = []

def create_tasks():
    title = input("Enter Your Task Title: ")
    description = input("Enter Your Task Description: ")
    tasks.append({"Task Title": title, "Task Description": description})
    print("✅ Task Created Successfully.")

This function prompts the user for a task title and description, then adds it to the task list.

Main Menu 🗂️

Create an interactive loop for user options:

while True:
    print("\nWelcome to the Interactive Task Manager")
    print("1. Add Task")
    print("2. View Task")
    print("3. Update Task")
    print("4. Delete Task")
    print("5. Exit")

    choice = input("Select an option from (1-5): ")

    if choice == '1':
        create_tasks()
    elif choice == '2':
        see_tasks()
    elif choice == '3':
        update_tasks()
    elif choice == '4':
        delete_tasks()
    elif choice == '5':
        print("Exiting the task manager.")
        break
    else:
        print("⚠️ Invalid option. Please select between 1 and 5.")

Viewing Tasks 👀

To view created tasks:

def see_tasks():
    if tasks:
        print("Available Tasks:")
        for idx, task in enumerate(tasks, start=1):
            print(f"{idx}. Task Title: {task['Task Title']}, Task Description: {task['Task Description']}")
    else:
        print("📭 No Tasks Available.")

Updating Tasks ✏️

The update_tasks() function enables flexible task updating:

def update_tasks():
    see_tasks()
    if tasks:
        tasks_index = int(input("Provide the Index of your task to be updated: ")) - 1
        if 0 <= tasks_index < len(tasks):
            new_task_title = input("Provide your new title or (Press Enter to keep current title): ")
            new_task_description = input("Provide your new description or (Press Enter to keep current description): ")
            if new_task_title: ""
                tasks[tasks_index]['Task Title'] = new_task_title
            if new_task_description: ""
                tasks[tasks_index]['Task Description'] = new_task_description
            print("✅ Task Updated")
        else:
            print("⚠️ Invalid Index.")
    else:
        print("📭 No Tasks Available.")

Deleting Tasks 🗑️

To remove unwanted tasks:

def delete_tasks():
    see_tasks()
    if tasks:
        tasks_index = int(input("Provide the Index of the task to be deleted: ")) - 1
        if 0 <= tasks_index < len(tasks):
            deleted_task = tasks.pop(tasks_index)
            print(f"🗑️ Task '{deleted_task['Task Title']}' deleted successfully.")
        else:
            print("⚠️ Invalid Index.")
    else:
        print("📭 No Tasks Available.")

Testing and Debugging 🔍

1. Testing the Add Function: Check if tasks are stored and displayed.
2. Testing the Update Function: Ensure title or description updates work independently.
3. Testing the Delete Function: Try deleting tasks and see if the list updates correctly.
4. Edge Cases: Test program behavior with no tasks, invalid inputs, etc.

Output 🎉

Conclusion 🏆

You’ve built a simple task manager using Python! You learned:

• Setting up a development environment
• Task management features like add, view, update, delete
• Testing and debugging techniques

Future Extensions 🚀

1. Add file-saving for persistence.
2. Add due dates for tasks.
3. Create categories for task organization.
