```jsx import React, { useState } from 'react'; const styles = { container: { maxWidth: '600px', margin: '0 auto', padding: '20px', }, form: { display: 'flex', flexDirection: 'column', marginBottom: '20px', }, input: { margin: '5px 0', padding: '5px', }, button: { margin: '5px 0', padding: '5px 10px', backgroundColor: '#4CAF50', color: 'white', border: 'none', cursor: 'pointer', }, task: { display: 'flex', alignItems: 'center', marginBottom: '10px', }, completed: { textDecoration: 'line-through', color: 'red', }, }; function TodoList() { const [tasks, setTasks] = useState([]); const [newTask, setNewTask] = useState({ description: '', category: '' }); const [editingTask, setEditingTask] = useState(null); const handleInputChange = (e) => { setNewTask({ ...newTask, [e.target.name]: e.target.value }); }; const handleSubmit = (e) => { e.preventDefault(); if (editingTask) { setTasks(tasks.map(task => task.id === editingTask.id ? { ...task, ...newTask } : task)); setEditingTask(null); } else { setTasks([...tasks, { id: Date.now(), ...newTask, completed: false }]); } setNewTask({ description: '', category: '' }); }; const toggleComplete = (id) => { setTasks(tasks.map(task => task.id === id ? { ...task, completed: !task.completed } : task)); }; const deleteTask = (id) => { setTasks(tasks.filter(task => task.id !== id)); }; const editTask = (task) => { setEditingTask(task); setNewTask({ description: task.description, category: task.category }); }; return ( <div style={styles.container}> <h1>Todo List</h1> <form onSubmit={handleSubmit} style={styles.form}> <input type="text" name="description" value={newTask.description} onChange={handleInputChange} placeholder="Task description" style={styles.input} /> <input type="text" name="category" value={newTask.category} onChange={handleInputChange} placeholder="Category" style={styles.input} /> <button type="submit" style={styles.button}> {editingTask ?

Make sure to have React installed in your project before using this code.

**Hello World in Python** ``` print("Hello, World!") ``` This code will output `Hello, World!` when run. **Explanation:** * `print()` is a built-in function in Python that prints its argument to the console. * The string `"Hello, World!"` is the argument passed to `print()`, which is then printed to the console. Save this code in a file with a `.py` extension (e.g., `hello.py`) and run it using Python (e.g., `python hello.py`) to see the output.

## Creating a Harry Potter-based Game on Roblox with Wands and Spells To create a Harry Potter-based game on Roblox, you'll need to create a wand and implement spells that can be cast using the left mouse click. Here's a step-by-step guide to help you achieve this: ### Creating the Wand 1. Create a new `Part` in the `Workspace` and rename it to "Wand". This will serve as the player's wand. 2. Add a `.LocalScript` to the Wand and name it "WandScript". 3. In the WandScript, add the following code to initialize the wand: ```lua local player = game.Players.LocalPlayer local wand = script.Parent -- Set the wand's properties wand.Handle = wand:WaitForChild("Handle") -- Assuming the handle is a child of the wand wand.Tip = wand:WaitForChild("Tip") -- Assuming the tip is a child of the wand ``` ### Implementing Spells with Left Click To implement spells with left click, you'll need to detect when the player clicks the left mouse button and then cast the corresponding spell. 1. Add a `UserInputService` to the WandScript to detect mouse clicks: ```lua local userInputService = game:GetService("UserInputService") -- Function to cast a spell when the left mouse button is clicked local function castSpell() -- Get the spell from the player's inventory or a preset spell local spell = getSpellFromInventory() -- Implement this function to get the spell from the player's inventory -- Cast the spell (more on this later) castSpellEffect(spell) end -- Connect the left mouse button click event to the castSpell function userInputService.InputBegan:Connect(function(input) if input.UserInputType == Enum.UserInputType.MouseButton1 then castSpell() end end) ``` ### Casting Spells To cast a spell, you'll need to create a function that will handle the spell's effects. Here's a basic implementation: ```lua local function castSpellEffect(spell) -- Get the spell's properties (e.g., spell name, damage, range, etc.) local spellName = spell.Name local damage = spell.Damage local range = spell.Range -- Create a spell effect (e.g., a fireball, a blast of air, etc.) local spellEffect = Instance.new("Explosion") spellEffect.Position = wand.Tip.Position spellEffect.Parent = workspace -- Apply the spell's effects (e.g., damage to enemies, environment, etc.) -- Implement this logic based on the spell's properties -- For example: local enemies = getEnemiesInRadius(wand.Tip.Position, range) for _, enemy in ipairs(enemies) do enemy:TakeDamage(damage) end -- Remove the spell effect after a short duration wait(1) spellEffect:Destroy() end ``` ### Adding Spells to the Player's Inventory To allow players to switch spells, you'll need to implement a system to store and retrieve spells from their inventory. You can do this using a `Folder` in the player's `StarterPack` or `Backpack`. 1. Create a `Folder` in the player's `StarterPack` or `Backpack` and name it "Spells". 2. Create new `Folder`s within the Spells folder to represent individual spells (e.g., "Fireball", "HealingBlast", etc.). 3. Add the spell's properties (e.g., damage, range, etc.) to the spell's folder as `IntValue`s or `StringValue`s. 4. Modify the `getSpellFromInventory` function to retrieve the currently selected spell from the player's inventory. Here's a basic implementation: ```lua local function getSpellFromInventory() local spellsFolder = game.Players.LocalPlayer.StarterPack.Spells local selectedSpell = spellsFolder:FindFirstChild("SelectedSpell") if selectedSpell then return selectedSpell end end ``` This is a basic outline to get you started. You can expand on this by adding more features, such as spell cooldowns, spell levels, and more. Remember to adjust the code to fit your specific game requirements and implement the necessary logic for handling spell effects, enemy AI, and other game mechanics. Good luck with your Harry Potter-based game on Roblox!

Proof-of-Work consensus mechanism 3. Transaction signing and verification using RSA 4. Network functionality for distributed nodes 5. Persistent storage using both file-based and SQLite database storage 6. A simple node server to handle basic network requests To make this production-ready, you would need to add more robust error handling, implement a more advanced consensus mechanism, add more comprehensive testing, and optimize for performance. Additionally, you'd want to implement a proper API, add more security features, and create a user interface for interacting with the blockchain.
