Python vs Javascript: Examples
Let us check examples of the programming languages Python and Javascript below.
Python Language
Predict house prices based on features like location, size, and number of bedrooms using Python language. First, we will use the Pandas library to clean and preprocess the dataset and apply machine learning libraries such as Scikit Learn to train the predictive model. You can present using matplotlib or Seaborn.| # Import required libraries import pandas as pd from sklearn.model_selection import train_test_split from sklearn.linear_model import LinearRegression from sklearn.metrics import mean_squared_error # Sample dataset data = { 'Size (sq ft)': [1500, 1700, 1900, 2100, 2300], 'Bedrooms': [3, 3, 4, 4, 5], 'Price ($)': [300000, 350000, 400000, 450000, 500000] } df = pd.DataFrame(data) # Features and target variable X = df[['Size (sq ft)', 'Bedrooms']] y = df['Price ($)'] # Split the data X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42) # Train the model model = LinearRegression() model.fit(X_train, y_train) # Predictions predictions = model.predict(X_test) # Evaluate the model mse = mean_squared_error(y_test, predictions) print(f"Mean Squared Error: {mse}") print(f"Predicted Prices: {predictions}") |
Javascript Example
Create a real time chat application and build a web based chat application where users can exchange messages in real time. Use React.js to create user interfaces.| const WebSocket = require('ws'); // Create WebSocket server const wss = new WebSocket.Server({ port: 8080 }); wss.on('connection', (ws) => { console.log('New client connected'); // Listen for messages from clients ws.on('message', (message) => { console.log(`Received: ${message}`); // Broadcast message to all connected clients wss.clients.forEach((client) => { if (client.readyState === WebSocket.OPEN) { client.send(message); } }); }); ws.on('close', () => { console.log('Client disconnected'); }); }); console.log('WebSocket server is running on ws://localhost:8080'); |
