app.run(debug=True)
Web Scraper with BeautifulSoup
# Install BeautifulSoup and Requests
pip install beautifulsoup4 requests
import requests
from bs4 import BeautifulSoup
url = 'http://example.com'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
for item in soup.find_all('h2'):
print(item.get_text())
Building a REST API with Flask and SQLAlchemy
# Install Flask and SQLAlchemy
pip install Flask SQLAlchemy
from flask import Flask, jsonify, request
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///data.db'
db = SQLAlchemy(app)
class Item(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(80))
@app.route('/items', methods=['GET'])
def get_items():
items = Item.query.all()
return jsonify([{'id': item.id, 'name': item.name} for item in items])
if __name__ == '__main__':
app.run(debug=True)
