Python vs Javascript: Examples

Python vs Javascript

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’);

Python Vs Javascript: Python Can Do Everything

While there are many programming languages available, Python remains the best option for web developers, programmers, analysts, data scientists and other professionals. Javascript is a lightweight scripting language which is used for web development and supported by most of the browsers worldwide.

When it comes to research work, analysis, high level coding on the server side then Python is the choice while Javascript can make your web page look attractive, interactive, dynamic, and running. Javascript runs directly on web browsers without any requirement for compilation and it also supports object oriented programming. With Javascript, you can enable DOM manipulation for responsive user interfaces.
