Python Code Examples

User Authentication System with Flask

            
from flask import Flask, render_template, redirect, url_for, request, session
from werkzeug.security import generate_password_hash, check_password_hash

app = Flask(__name__)
app.secret_key = 'your_secret_key'

users = {}

@app.route('/register', methods=['GET', 'POST'])
def register():
    if request.method == 'POST':
        username = request.form['username']
        password = generate_password_hash(request.form['password'])
        users[username] = password
        return redirect(url_for('login'))
    return render_template('register.html')

@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'POST':
        username = request.form['username']
        password = request.form['password']
        if username in users and check_password_hash(users[username], password):
            session['username'] = username
            return redirect(url_for('dashboard'))
    return render_template('login.html')

@app.route('/dashboard')
def dashboard():
    return f"Welcome {session['username']}!"

if __name__ == '__main__':
    app.run(debug=True)
            
        

E-Commerce Website with Django

            
from django.db import models

class Product(models.Model):
    name = models.CharField(max_length=100)
    price = models.DecimalField(max_digits=10, decimal_places=2)
    description = models.TextField()

class Order(models.Model):
    product = models.ForeignKey(Product, on_delete=models.CASCADE)
    quantity = models.PositiveIntegerField()
    created_at = models.DateTimeField(auto_now_add=True)
            
        

Real-World Applications

Python web development can be applied in various fields, enhancing productivity and efficiency. Here are some notable applications:
