Python vs JavaScript I/O Patterns
Python
File Operations
# Python File I/O with automatic resource management
with open('data.txt', 'w') as f:
f.write('Hello, I/O World!')
# Reading with error handling
try:
with open('data.txt', 'r') as f:
content = f.read()
print(content)
except FileNotFoundError:
print("File not found!")
JavaScript
File Operations
// JavaScript File I/O with Promises
const fs = require('fs').promises;
// Async/await pattern
async function handleFile() {
try {
await fs.writeFile('data.txt', 'Hello, I/O World!');
const content = await fs.readFile('data.txt', 'utf8');
console.log(content);
} catch (error) {
console.error('File operation failed:', error);
}
}
Python
Socket Communication
import socket
# TCP Socket Server
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(('localhost', 8000))
server.listen(5)
while True:
client, addr = server.accept()
data = client.recv(1024)
client.send(b'Echo: ' + data)
client.close()
JavaScript
Socket Communication
const net = require('net');
// TCP Socket Server
const server = net.createServer((socket) => {
socket.on('data', (data) => {
socket.write('Echo: ' + data);
});
socket.on('end', () => {
console.log('Client disconnected');
});
});
server.listen(8000, () => {
console.log('Server running on port 8000');
});
