Python Code Examples
Blog Application Example
from flask import Flask, render_template, request, redirect
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///blog.db'
db = SQLAlchemy(app)
class Post(db.Model):
id = db.Column(db.Integer, primary_key=True)
title = db.Column(db.String(100), nullable=False)
content = db.Column(db.Text, nullable=False)
@app.route('/')
def index():
posts = Post.query.all()
return render_template('index.html', posts=posts)
@app.route('/add', methods=['POST'])
def add_post():
new_post = Post(title=request.form['title'], content=request.form['content'])
db.session.add(new_post)
db.session.commit()
return redirect('/')
if __name__ == "__main__":
app.run(debug=True)
E-commerce Example
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/products')
def products():
return render_template('products.html')
if __name__ == "__main__":
app.run(debug=True)
Real-World Applications
Python web development is deployed in various significant applications across the web. For instance:
- Instagram: Built on Django, Instagram manages millions of user-uploaded images and videos.
- Spotify: Utilizes Python for backend services, using its flexibility to manage music streaming and data analysis.
- Reddit: Originally built with Lisp, moved to Python for its readability and ease of integration.
